GENERAL DESCRIPTION
• Performance range
The Samsung M470L1624DT0 is 16M bit x 64 Double Data
Part No.
Max Freq.
Interface
Rate SDRAM high density memory modules.
M470L1624DT0-C(L)B3 166MHz(6ns@CL=2.5)
M470L1624DT0-C(L)A2 133MHz(7.5ns@CL=2)
M470L1624DT0-C(L)B0 133MHz(7.5ns@CL=2.5)
The Samsung M470L1624DT0 consists of four CMOS 16M x
16 bit with 4banks Double Data Rate SDRAMs in 66pin TSOP-
II(400mil) packages mounted on a 200pin glass-epoxy sub-
strate. Four 0.1uF decoupling capacitors are mounted on the
printed circuit board in parallel for each DDR SDRAM.
The M470L1624DT0 is Dual In-line Memory Modules and
intended for mounting into 200pin edge connector sockets.
Synchronous design allows precise cycle control with the use
of system clock. Data I/O transactions are possible on both
edges of DQS. Range of operating frequencies, programmable
latencies and burst lengths allow the same device to be useful
for a variety of high bandwidth, high performance memory sys-
tem applications.

Notes 1. Includes ± 25mV margin for DC offset on VREF, and a combined total of ± 50mV margin for all AC noise and DC offset on VREF,
bandwidth limited to 20MHz. The DRAM must accommodate DRAM current spikes on VREF and internal DRAM noise coupled
TO VREF, both of which may result in VREF noise. VREF should be de-coupled with an inductance of ≤ 3nH.
2.V is not applied directly to the device. V is a system supply for signal termination resistors, is expected to be set equal to
TT
TT
VREF, and must track variations in the DC level of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on CK.
4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the pad in
simulation. The AC and DC input specifications are relative to a VREF envelop that has been bandwidth limited to 200MHZ.
5. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the dc level of the same.
6. These charactericteristics obey the SSTL-2 class II standards.

1. Maximum burst refresh cycle : 8
2. The specific requirement is that DQS be valid(High or Low) on or before this CK edge. The case shown(DQS going from
High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was in progress,
DQS could be High at this time, depending on tDQSS.
3. The maximum limit for this parameter is not a device limit. The device will operate with a great value for this parameter,
but system performance (bus turnaround) will degrade accordingly.
4. A write command can be applied with tRCD satisfied after this command.
5. For registered DIMMs, tCL and tCH are ≥ 45% of the period including both the half period jitter (tJIT(HP)) of the PLL and the half period
jitter due to crosstalk (tJIT(crosstalk)) on the DIMM.

This derating table is used to increase tDS/tDH in the case where the DQ and DQS slew rates differ. The Delta Rise/Fall Rate
is calated as 1/SlewRate1-1/SlewRate2. For example, if slew rate 1 = 5V/ns and slew rate 2 =.4V/ns then the Delta Rise/Fall
Rate =-0/5ns/V. Input S/H slew rate based on larger of AC-AC delta rise/fall rate and DC-DC delta rise/fall rate.
10. This parameter is fir system simulation purpose. It is guranteed by design.
11. For each of the terms, if not already an integer, round to the next highest integer. tCK is actual to the system clock cycle time.

The following table specifies derating values for the specifications listed if the single-ended clock skew rate is less than 1.0V/ns.

No operation (NOP) : Not defined
Note : 1. OP Code : Operand Code. A0 ~ A12 & BA0 ~ BA1 : Program keys. (@EMRS/MRS)
2. EMRS/ MRS can be issued only at all banks precharge state.
A new command can be issued 2 clock cycles after EMRS or MRS.
3. Auto refresh functions are same as the CBR refresh of DRAM.
The automatical precharge without row precharge command is meant by "Auto".
Auto/self refresh can be issued only at all banks precharge state.
4. BA0 ~ BA1 : Bank select addresses.
If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected.
If BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected.
If BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank C is selected.
If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected.
5. If A10/AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected.
6. During burst write with auto precharge, new read/write command can not be issued.
Another bank read/write command can be issued after the end of burst.
New row active of the associated bank can be issued at tRP after the end of burst.
7. Burst stop command is valid at every burst length.
8. DM sampled at the rising and falling edges of the DQS and Data-in are masked at the both edges (Write DM latency is 0).
9. This combination is not defined for any function, which means "No Operation(NOP)" in DDR SDRAM.
