Description
The 1-Gbit DDR2 DRAM is a high-speed Double-Data-Rate-
Two CMOS Synchronous DRAM device containing
1,073,741,824 bits and internally configured as an octal bank
DRAM.
The 1-Gbit device is organized as 16 Mbit ×8 I/O ×8 banks or
8 Mbit ×16 I/O ×8 banks chip.
All of the control and address inputs are synchronized with a
pair of externally supplied differential clocks. Inputs are
latched at the cross point of differential clocks (CK rising and
CK falling). All I/Os are synchronized with a single ended
DQS or differential DQS-DQS pair in a source synchronous
fashion.
These synchronous devices achieve high speed transfer
rates starting at 400 Mb/sec/pin for general applications. See
Table 1 for performance figures.
A 17 bit address bus for ×8 organised components and a
16 bit address bus for ×16 components is used to convey row,
column and bank address information in a RAS-CAS
multiplexing style.
The device is designed to comply with all DDR2 DRAM key
features:
The DDR2 device operates with a 1.8 V ± 0.1 V power
supply. An Auto-Refresh and Self-Refresh mode is provided
along with various power-saving power-down modes.
1. Posted CAS with additive latency.
2. Write latency = read latency - 1.
3. Normal and weak strength data-output driver.
4. Off-Chip Driver (OCD) impedance adjustment.
5. On-Die Termination (ODT) function.
The functionality described and the timing specifications
included in this data sheet are for the DLL Enabled mode of
operation.
The DDR2 SDRAM is available in TFBGA package.

1. UDQS/UDQS is data strobe for DQ[15:8], LDQS/LDQS is data strobe for DQ[7:0]
2. LDM is the data mask signal for DQ[7:0], UDM is the data mask signal for DQ[15:8]
3. VDDL and VSSDL are power and ground for the DLL. VDDL is connected to VDD on the device. VSSDL is connected to VSS
internally. VDD, VDDQ and VSSQ are isolated on the device.

1) w = write only register bits
2) Number of clock cycles for write recovery during auto-precharge. WR in clock cycles is calculated by dividing tWR (in ns) by tCK (in ns) and
rounding up to the next integer: WR [cycles] ≥ tWR (ns) / tCK (ns). The mode register must be programmed to fulfill the minimum requirement
for the analogue tWR timing WRMIN is determined by tCK.MAX and WRMAX is determined by tCK.MIN

2) When DRAM is operated at 85°C ≤ TCase ≤ 95°C the extended self refresh rate must be enabled by setting bit A7 to 1 before the self refresh
mode can be entered.
3) If PASR (Partial Array Self Refresh) is enabled, data located in areas of the array beyond the specified location will be lost if self refresh
is entered. Data integrity will be maintained if tREF conditions are met and no Self Refresh command is issued.

1) The state of ODT does not affect the states described in this table. The ODT function is not available during Self Refresh.
2) “X” means H or L (but a defined logic level).
3) Operation that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down
and then restarted through the specified initialization sequence before normal operation can continue.
4) All DDR2 SDRAM commands are defined by states of CS, WE, RAS, CAS and CKE at the rising edge of the clock.
5) Bank addresses BA[2:0] determine which bank is to be operated upon. For (E)MRS BA[2:0] selects an (Extended) Mode Register.
6) All banks must be in a precharged idle state, CKE must be high at least for tXP and all read/write bursts must be finished before the
(Extended) Mode Register set Command is issued.
7)
VREF must be maintained during Self Refresh operation.
8) Self Refresh Exit is asynchronous.
9) Burst reads or writes at BL = 4 cannot be terminated. See Chapter 3.5 for details.
10) The Power Down Mode does not perform any refresh operations. The duration of Power Down is therefore limited by the refresh
requirements.

Refer to the Command Truth Table
1) Current state is the state of the DDR2 SDRAM immediately prior to clock edge N.
2) Command (N) is the command registered at clock edge N, and Action (N) is a result of Command (N).
3) The state of ODT does not affect the states described in this table. The ODT function is not available during Self Refresh. .
4) CKE must be maintained HIGH while the device is in OCD calibration mode.
5) Operation that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down
and then restarted through the specified initialization sequence before normal operation can continue.
6) CKE (N) is the logic state of CKE at clock edge N; CKE (N-1) was the state of CKE at the previous clock edge.
7) The Power-Down Mode does not perform any refresh operations. The duration of Power-Down Mode is therefor limited by the refresh
requirements.
8) “X” means “don’t care (including floating around VREF)” in Self Refresh and Power Down. However ODT must be driven HIGH or LOW in
Power Down if the ODT function is enabled (Bit A2 or A6 set to 1 in EMRS(1)).
9) All states and sequences not shown are illegal or reserved unless explicitly described elsewhere in this document.
10) Valid commands for Power-Down Entry and Exit are NOP and DESELECT only.
11) tCKE.MIN of 3 clocks means CKE must be registered on three consecutive positive clock edges. CKE must remain at the valid input level the
entire time it takes to achieve the 3 clocks of registration. Thus, after any CKE transition, CKE may not transition from its valid level during
the time period of tIS + 2 × tCK + tIH.
12) VREF must be maintained during Self Refresh operation.
13) On Self Refresh Exit DESELECT or NOP commands must be issued on every clock edge occurring during the tXSNR period. Read
commands may be issued only after tXSRD (200 clocks) is satisfied.
14) Valid commands for Self Refresh Exit are NOP and DESELCT only.
15) Power-Down and Self Refresh can not be entered while Read or Write operations, (Extended) mode Register operations, Precharge or
Refresh operations are in progress.
16) Self Refresh mode can only be entered from the All Banks Idle state.
17) Must be a legal command as defined in the Command Truth Table.

DC & AC Characteristics
DDR2 SDRAM pin timing are specified for either single ended
or differential mode depending on the setting of the EMRS(1)
“Enable DQS” mode bit; timing advantages of differential
mode are realized in system design. The method by which the
DDR2 SDRAM pin timing are measured is mode dependent.
In single ended mode, timing relationships are measured
In differential mode, these timing relationships are measured
relative to the crosspoint of DQS and its complement, DQS.
This distinction in timing methods is verified by design and
characterization but not subject to production test. In single
ended mode, the DQS (and RDQS) signals are internally
disabled and don’t care.

1) SSTL_18 test load for VOH and VOL is different from the referenced load . The SSTL_18 test load has a 20 Ohm series resistor additionally
to the 25 Ohm termination resistor into VTT. The SSTL_18 definition assumes that ± 335 mV must be developed across the effectively 25
Ohm termination resistor (13.4 mA × 25 Ohm = 335 mV). With an additional series resistor of 20 Ohm this translates into a minimum
requirement of 603 mV swing relative to VTT, at the ouput device (13.4 mA × 45 Ohm = 603 mV).

2) Impedance measurement condition for output source dc current: VDDQ = 1.7 V, VOUT = 1420 mV; (VOUT–VDDQ) / IOH must be less than 23.4
ohms for values of VOUT between VDDQ and VDDQ – 280 mV. Impedance measurement condition for output sink dc current: VDDQ = 1.7 V;
V
OUT = –280 mV; VOUT / IOL must be less than 23.4 Ohms for values of VOUT between 0 V and 280 mV.
3) Mismatch is absolute value between pull-up and pull-down, both measured at same temperature and voltage.
4) This represents the step size when the OCD is near 18 ohms at nominal conditions across all process parameters and represents only the
DRAM uncertainty. A 0 Ohm value (no calibration) can only be achieved if the OCD impedance is 18 ± 0.75 Ohms under nominal
conditions.
5) The absolute value of the Slew Rate as measured from DC to DC is equal to or greater than the Slew Rate as measured from AC to AC.
This is verified by design and characterization but not subject to production test.
6) Timing skew due to DRAM output Slew Rate mis-match between DQS / DQS and associated DQ’s is included in tDQSQ and tQHS
specification.
7) DRAM output Slew Rate specification applies to 400, 533 and 667 MT/s speed bins.

1) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew
Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended mode. .
2) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS,
input reference level is the crosspoint when in differential strobe mode. CKDQS RDQS
3) Inputs are not recognized as valid until VREF stabilizes. During the period before VREF stabilizes, CKE = 0.2 x VDDQ
4) The output timing reference voltage level is VTT.
5) tRAS.MAX is calculated from the maximum amount of time a DDR2 device can operate without a refresh command which is equal to 9 x tREFI

1) VDDQ = 1.8 V ± 0.1V; VDD = 1.8 V ± 0.1 V.
2) Timing that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down
and then restarted through the specified initialization sequence before normal operation can continue.
3) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew
Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended mode.
4) The CK / CK input reference level (for timing reference to CK / CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS,
input reference level is the crosspoint when in differential strobe mode. DQS RDQS
5) Inputs are not recognized as valid until VREF stabilizes. During the period before VREF stabilizes, CKE = 0.2 x VDDQ is recognized as low.
6) The output timing reference voltage level is VTT.
7) New units, ‘tCK.AVG‘ and ‘nCK‘, are introduced in DDR2–667 and DDR2–800. Unit ‘tCK.AVG‘ represents the actual tCK.AVG of the input clock
under operation. Unit ‘nCK‘ represents one clock cycle of the input clock, counting the actual clock edges. Note that in DDR2–400 and

DDR2–533, ‘tCK‘ is used for both concepts. Example: tXP = 2 [nCK] means; if Power Down exit is registered at Tm, an Active command
may be registered at Tm + 2, even if (Tm + 2 - Tm) is 2 x tCK.AVG + tERR.2PER(Min)
.
8) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tERR(6-10per) of the input clock. (output
deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tERR(6-10PER).MIN = – 272
ps and tERR(6- 10PER).MAX = + 293 ps, then tDQSCK.MIN(DERATED) = tDQSCK.MIN – tERR(6-10PER).MAX = – 400 ps – 293 ps = – 693 ps and
t
DQSCK.MAX(DERATED) = tDQSCK.MAX – tERR(6-10PER).MIN = 400 ps + 272 ps = + 672 ps. Similarly, tLZ.DQ for DDR2–667 derates to tLZ.DQ.MIN(DERATED)
= - 900 ps – 293 ps = – 1193 ps and tLZ.DQ.MAX(DERATED) = 450 ps + 272 ps = + 722 ps. (Caution on the MIN/MAX usage!)
9) Input clock jitter spec parameter. These parameters and the ones in Chapter 7.3 are referred to as 'input clock jitter spec parameters' and
these parameters apply to DDR2–667 and DDR2–800 only. The jitter specified is a random jitter meeting a Gaussian distribution.
10) These parameters are specified per their average values, however it is understood that the relationship as defined in Chapter 7.3 between
the average timing and the absolute instantaneous timing holds all the times (min. and max of SPEC values are to be used for calculations
of Chapter 7.3).
11) tCKE.MIN of 3 clocks means CKE must be registered on three consecutive positive clock edges. CKE must remain at the valid input level the
entire time it takes to achieve the 3 clocks of registration. Thus, after any CKE transition, CKE may not transition from its valid level during
the time period of tIS + 2 x tCK + tIH.
12) DAL = WR + RU{tRP(ns) / tCK(ns)}, where RU stands for round up. WR refers to the tWR parameter stored in the MRS. For tRP, if the result
of the division is not already an integer, round up to the next highest integer. tCK refers to the application clock period. Example: For
DDR2–533 at tCK = 3.75 ns with tWR programmed to 4 clocks. tDAL = 4 + (15 ns / 3.75 ns) clocks = 4 + (4) clocks = 8 clocks.
13) tDAL.nCK = WR [nCK] + tnRP.nCK = WR + RU{tRP [ps] / tCK.AVG[ps] }, where WR is the value programmed in the EMR.
14) Input waveform timing tDH with differential data strobe enabled MR[bit10] = 0, is referenced from the differential data strobe crosspoint to
the input signal crossing at the VIH.DC level for a falling signal and from the differential data strobe crosspoint to the input signal crossing
at the VIL.DC level for a rising signal applied to the device under test. DQS, DQS signals must be monotonic between VIL.DC.MAX and
V
IH.DC.MIN. See Figure 8.
15) tDQSQ: Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers as well as output
slew rate mismatch between DQS / DQS and associated DQ in any given cycle.
16) These parameters are measured from a data strobe signal ((L/U/R)DQS / DQS) crossing to its respective clock signal (CK / CK) crossing.
The spec values are not affected by the amount of clock jitter applied (i.e. tJIT.PER, tJIT.CC, etc.), as these are relative to the clock signal
crossing. That is, these parameters should be met whether clock jitter is present or not.
17) Input waveform timing tDS with differential data strobe enabled MR[bit10] = 0, is referenced from the input signal crossing at the VIH.AC level
to the differential data strobe crosspoint for a rising signal, and from the input signal crossing at the VIL.AC level to the differential data strobe
crosspoint for a falling signal applied to the device under test. DQS, DQS signals must be monotonic between Vil(DC)MAX and Vih(DC)MIN. See
Figure 8.
18) If tDS or tDH is violated, data corruption may occur and the data must be re-written with valid data before a valid READ can be executed.
19) These parameters are measured from a data signal ((L/U)DM, (L/U)DQ0, (L/U)DQ1, etc.) transition edge to its respective data strobe signal
((L/U/R)DQS / DQS) crossing.
20) tHP is the minimum of the absolute half period of the actual input clock. tHP is an input parameter but not an input specification parameter.
It is used in conjunction with tQHS to derive the DRAM output timing tQH. The value to be used for tQH calculation is determined by the
following equation; tHP = MIN (tCH.ABS, tCL.ABS), where, tCH.ABS is the minimum of the actual instantaneous clock high time; tCL.ABS is the
minimum of the actual instantaneous clock low time.
21) tHZ and tLZ transitions occur in the same access time as valid data transitions. These parameters are referenced to a specific voltage level
which specifies when the device output is no longer driving (tHZ), or begins driving (tLZ) .
22) input waveform timing is referenced from the input signal crossing at the VIL.DC level for a rising signal and VIH.DC for a falling signal applied
to the device under test. See Figure 9.
23) Input waveform timing is referenced from the input signal crossing at the VIH.AC level for a rising signal and VIL.AC for a falling signal applied
to the device under test. See Figure 9.
24) These parameters are measured from a command/address signal (CKE, CS, RAS, CAS, WE, ODT, BA0, A0, A1, etc.) transition edge to
its respective clock signal (CK / CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT.PER, tJIT.CC
,
etc.), as the setup and hold are relative to the clock signal crossing that latches the command/address. That is, these parameters should
be met whether clock jitter is present or not.
25) tQH = tHP – tQHS, where: tHP is the minimum of the absolute half period of the actual input clock; and tQHS is the specification value under
the max column. {The less half-pulse width distortion present, the larger the tQH value is; and the larger the valid data eye will be.}
Examples: 1) If the system provides tHP of 1315 ps into a DDR2–667 SDRAM, the DRAM provides tQH of 975 ps minimum. 2) If the system
provides tHP of 1420 ps into a DDR2–667 SDRAM, the DRAM provides tQH of 1080 ps minimum.
26) tQHS accounts for: 1) The pulse duration distortion of on-chip clock circuits, which represents how well the actual tHP at the input is
transferred to the output; and 2) The worst case push-out of DQS on one transition followed by the worst case pull-in of DQ on the next
transition, both of which are independent of each other, due to data pin skew, output pattern effects, and pchannel to n-channel variation
of the output drivers.
27) The Auto-Refresh command interval has be reduced to 3.9 µs when operating the DDR2 DRAM in a temperature range between 85 °C
and 95 °C.

28) 0 °C≤ TCASE ≤ 85 °C.
29) 85 °C < TCASE ≤ 95 °C.
30) A maximum of eight Refresh commands can be posted to any given DDR2 SDRAM, meaning that the maximum absolute interval between
any Refresh command and the next Refresh command is 9 x tREFI
.
31) tRPST end point and tRPRE begin point are not referenced to a specific voltage level but specify when the device output is no longer driving
(tRPST), or begins driving (tRPRE). Figure 7 shows a method to calculate these points when the device is no longer driving (tRPST), or begins
driving (tRPRE) by measuring the signal at two different voltages. The actual voltage measurement points are not critical as long as the
calculation is consistent.
32) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT.PER of the input clock. (output
deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tJIT.PER.MIN = – 72 ps
and tJIT.PER.MAX = + 93 ps, then tRPRE.MIN(DERATED) = tRPRE.MIN + tJIT.PER.MIN = 0.9 x tCK.AVG – 72 ps = + 2178 ps and tRPRE.MAX(DERATED) = tRPRE.MAX
+ tJIT.PER.MAX = 1.1 x tCK.AVG + 93 ps = + 2843 ps. (Caution on the MIN/MAX usage!).
33) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT.DUTY of the input clock. (output
deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR2–667 SDRAM has tJIT.DUTY.MIN = – 72 ps
and tJIT.DUTY.MAX = + 93 ps, then tRPST.MIN(DERATED) = tRPST.MIN + tJIT.DUTY.MIN = 0.4 x tCK.AVG – 72 ps = + 928 ps and tRPST.MAX(DERATED) = tRPST.MAX
+ tJIT.DUTY.MAX = 0.6 x tCK.AVG + 93 ps = + 1592 ps. (Caution on the MIN/MAX usage!).
34) For these parameters, the DDR2 SDRAM device is characterized and verified to support tnPARAM = RU{tPARAM / tCK.AVG}, which is in clock
cycles, assuming all input clock jitter specifications are satisfied. For example, the device will support tnRP = RU{tRP / tCK.AVG}, which is in
clock cycles, if all input clock jitter specifications are met. This means: For DDR2–667 5–5–5, of which tRP = 15 ns, the device will support
t
nRP = RU{tRP / tCK.AVG} = 5, i.e. as long as the input clock jitter specifications are met, Precharge command at Tm and Active command at
Tm + 5 is valid even if (Tm + 5 - Tm) is less than 15 ns due to input clock jitter.
35) tWTR is at lease two clocks (2 x tCK) independent of operation frequency.

2) Timing that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down
and then restarted through the specified initialization sequence before normal operation can continue.
3) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew
Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended mode.

input reference level is the crosspoint when in differential strobe mode. DQS RDQS
5) Inputs are not recognized as valid until VREF stabilizes. During the period before VREF stabilizes, CKE = 0.2 x VDDQ is recognized as low.
6) The output timing reference voltage level is VTT.
7) For each of the terms, if not already an integer, round to the next highest integer. tCK refers to the application clock period. WR refers to
the WR parameter stored in the MR.
8) The clock frequency is allowed to change during self-refresh mode or precharge power-down mode.
9) For timing definition, refer to the Component data sheet.
10) Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers as well as output Slew Rate
mis-match between DQS / DQS and associated DQ in any given cycle.
11) MIN (tCL, tCH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device (i.e. this value can
be greater than the minimum specification limits for tCL and tCH).
12) The tHZ, tRPST and tLZ, tRPRE parameters are referenced to a specific voltage level, which specify when the device output is no longer driving
(tHZ, tRPST), or begins driving (tLZ, tRPRE). tHZ and tLZ transitions occur in the same access time windows as valid data transitions.These
parameters are verified by design and characterization, but not subject to production test.
13) The Auto-Refresh command interval has be reduced to 3.9 µs when operating the DDR2 DRAM in a temperature range between 85 °C
and 95 °C.
14) 0 °C≤ TCASE ≤ 85 °C.
15) 85 °C < TCASE ≤ 95 °C.
16) A maximum of eight Refresh commands can be posted to any given DDR2 SDRAM, meaning that the maximum absolute interval between
any Refresh command and the next Refresh command is 9 x tREFI
.
17) The tRRD timing parameter depends on the page size of the DRAM organization.
18) The maximum limit for the tWPST parameter is not a device limit. The device operates with a greater value for this parameter, but system
performance (bus turnaround) degrades accordingly.
19) Minimum tWTR is two clocks when operating the DDR2-SDRAM at frequencies ≤ 200 ΜΗz.
20) User can choose two different active power-down modes for additional power saving via MRS address bit A12. In “standard active power-
down mode” (MR, A12 = “0”) a fast power-down exit timing tXARD can be used. In “low active power-down mode” (MR, A12 =”1”) a slow
power-down exit timing tXARDS has to be satisfied.
21) WR must be programmed to fulfill the minimum requirement for the tWR timing parameter, where WRMIN[cycles] = tWR(ns)/tCK(ns) rounded
up to the next integer value. tDAL = WR + (tRP/tCK). For each of the terms, if not already an integer, round to the next highest integer. tCK
refers to the application clock period. WR refers to the WR parameter stored in the MRS.

Jitter Definition and Clock Jitter Specification
Generally, jitter is defined as “the short-term variation of a signal with respect to its ideal position in time”. Input clock jitter
specification parameters are applicable to DDR2-667, DDR2-800 and DDR2-1066.
The following table provides an overview of the terminology.

1) ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on. ODT turn on time max is when
the ODT resistance is fully on. Both are measured from tAOND, which is interpreted as 2 clock cycles after the clock edge that registered a
first ODT HIGH counting the actual input clock edges.
2) Timings are specified with DQs and DM input slew rate of 1.0V/ns. See Specific Notes on derating for other slew rate values.
3) When the device is operated with input clock jitter, this parameter needs to be derated by the actual tERR(6-10per) of the input clock (output
deratings are relative to the SDRAM input clock).
For example, if the measured jitter into a DDR2-1066 SDRAM has tERR(6-10per).MIN = - 202 ps and tERR(6-10per).MAX = + 223 ps, then
t
DQSCK.MIN(derated) = tDQSCK.MIN - tERR(6-10per).MAX = - 300 ps - 223 ps = - 523 ps and tDQSCK.MAX(derated) = tDQSCK.MAX - tERR(6-10per).MIN = 300 ps +
202 ps = + 502 ps.
Similarly, tLZ.DQ for DDR2-1066 derates to tLZ.DQ,min(derated) = - 700 ps - 223 ps = - 923 ps and
t
LZ.DQ.MAX(derated) = 350 ps + 202 ps = + 552 ps. (Caution on the min/max usage!)
4) ODT turn off time min is when the device starts to turn off ODT resistance. ODT turn off time max is when the bus is in high impedance.
Both are measured from tAOFD, which is interpreted as 0.5 x tCK.AVG [ns] after the second trailing clock edge counting from the clock edge
that registered a first ODT LOW and by counting the actual input clock edges. For DDR2-1066, this is 0.9375 [ns] (= 0.5 x 1.875 [ns]) after
the second trailing clock edge counting from the clock edge that registered a first ODT LOW and by counting the actual input clock edges.
5) For tAOFD of DDR2-1066, the 1/2 clock of nCK in the 2.5 x nCK assumes a tCH.AVG, average input clock HIGH pulse width of 0.5 relative to
t
CK.AVG. tAOF.MIN and tAOF.MAX should each be derated by the same amount as the actual amount of tCH.AVG offset present at the DRAM input
with respect to 0.5. For example, if an input clock has a worst case tCH.AVG of 0.48, the tAOF.MAX should be derated by subtracting 0.02 x
CK.AVG from it, whereas if an input clock has a worst case tCH.AVG of 0.52, the tAOF.MAX should be derated by adding 0.02 x tCK.AVG to it.
Therefore, we have; tAOF.MIN(derated) = tAC.MIN - [0.5 - Min(0.5, tCH.AVG.MIN)] x tCK.AVG AOF.MAX(derated) = tAC.MAX + 0.6 + [Max(0.5, tCH.AVG.MAX) - 0.5]
t
t
x tCK.AVGortAOF.MIN(derated) = Min(tAC.MIN, tAC.MIN - [0.5 - tCH.AVG:MIN] x tCK.AVG)tAOF:MAX(derated) = 0.6 + Max(tAC.MAX, tAC.MAX + [tCH:AVG:MAX - 0.5] x t
CK.AVG) where tCH.AVG.MIN and tCH.AVG.MAX are the minimum and maximum of tCH.AVG actually measured atthe DRAM input balls. Note that
these deratings are in addition to the tAOF derating per input clock jitter, i.e. tJIT(duty) and tERR(6-10per). However tAC values used in the equations
shown above are from the timing parameter table and are not derated. Thus the final derated values for tAOF aretAOF.MIN(derated_final)
=
t
t
AOF.MIN(derated) + { - tJIT.DUTY:MAX - tERR(6-10per).MAX
AOF.MAX(derated_final) = tAOF.MAXx(derated) + { - tJIT.DUTY.MIN - tERR(6-10per).MIN
}
}
6) When the device is operated with input clock jitter, this parameter needs to be derated by { - tJIT(duty),max - tERR(6-10per),max } and { - tJIT(duty),min
- tERR(6-10per),min } of the actual input clock. (output deratings are relative to the SDRAM input clock.)
For example, if the measured jitter into a DDR2-1066 SDRAM has tERR(6-10per),min = - 202 ps, tERR(6-10per),max = + 223 ps, tJIT(duty),min = - 66 ps
and tJIT(duty).MAX = + 74 ps, then tAOF,min(derated) = tAOF,min + { - tJIT(duty),max - tERR(6-10per),max } = - 350 ps + { - 74 ps - 223 ps} = - 647 ps and
t
AOF,max(derated) = tAOF.MAX + { - tJIT(duty),min - tERR(6-10per),min } = 950 ps + { 66 ps + 202 ps } = + 1218 ps. (Caution on the min/max usage!)

1) New units, “tCK.AVG” and “nCK”, are introduced in DDR2-667 and DDR2-800 Unit “tCK.AVG” represents the actual tCK.AVG of the input clock
under operation. Unit “nCK” represents one clock cycle of the input clock, counting the actual clock edges. Note that in DDR2-400 and
DDR2-533, “tCK” is used for both concepts. Example: tXP = 2 [nCK] means; if Power Down exit is registered at Tm, an Active command may
be registered at Tm + 2, even if (Tm + 2 - Tm) is 2 x tCK.AVG + tERR.2PER(Min)
.
2) ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on. ODT turn on time max is when
the ODT resistance is fully on. Both are measured from tAOND, which is interpreted differently per speed bin. For DDR2-667/800 tAOND is
2 clock cycles after the clock edge that registered a first ODT HIGH counting the actual input clock edges.
3) ODT turn off time min is when the device starts to turn off ODT resistance. ODT turn off time max is when the bus is in high impedance.
Both are measured from tAOFD, which is interpreted differently per speed bin. For DDR2-667/800, if tCK(avg) = 3 ns is assumed,
t
AOFD is 1.5 ns (= 0.5 x 3 ns) after the second trailing clock edge counting from the clock edge that registered a first ODT LOW and by
counting the actual input clock edges.
