GENERAL DESCRIPTION
• Performance range
The Samsung M390S1723DT1 is a 16M bit x 72 Synchronous
Dynamic RAM high density memory module. The Samsung
M390S1723DT1 consists of nine CMOS 16Mx8 bit Synchro-
nous DRAMs in TSOP-II 400mil packages, two 18-bits Drive
ICs for input control signal and one 2K EEPROM in 8-pin
TSSOP package for Serial Presence Detect on a 168pin glass-
epoxy substrate. One 0.22uF and two 0.0022uF decoupling
capacitors are mounted on the printed circuit board in parallel
for each SDRAM. The M390S1723DT1 is a Dual In-line Mem-
ory Module and is intented for mounting into 168-pin edge con-
nector sockets.

• Burst mode operation
• Auto & self refresh capability (4096 Cycles/64ms)
• LVTTL compatible inputs and outputs
• Single 3.3V ± 0.3V power supply
• MRS cycle with address key programs
Latency (Access from column address)
Burst length (1, 2, 4, 8 & Full page)
Data scramble (Sequential & Interleave)
• All inputs are sampled at the positive going edge of the
system clock
• Serial presence detect with EEPROM
• PCB : Height (1,500mil), double sided component
Synchronous design allows precise cycle control with the use
of system clock. I/O transactions are possible on every clock
cycle. Range of operating frequencies, programmable latencies

PIN CONFIGURATION DESCRIPTION
Pin
Name
System clock
Input Function
CLK
CS
Active on the positive going edge to sample all inputs.
Disables or enables device operation by masking or enabling all inputs except
CLK, CKE and DQM
Chip select
Masks system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one cycle prior to new command.
Disable input buffers for power down in standby.
CKE
Clock enable
CKE should be enabled 1CLK+tss prior to valid command.
Row/column addresses are multiplexed on the same pins.
Row address : RA0 ~ RA11, Column address : CA0 ~ CA9
A0 ~ A11
BA0 ~ BA1
RAS
Address
Selects bank to be activated during row address latch time.
Selects bank for read/write during column address latch time.
Bank select address
Row address strobe
Column address strobe
Write enable
Latches row addresses on the positive going edge of the CLK with RAS low.
Enables row access & precharge.
Latches column addresses on the positive going edge of the CLK with CAS low.
Enables column access.
CAS
Enables write operation and row precharge.
Latches data in starting from CAS, WE active.
WE
Makes data output Hi-Z, tSHZ after the clock and masks the output.
Blocks data input when DQM active. (Byte masking)
DQM0 ~ 7
Data input/output mask
The device operates in the transparent mode when REGE is low. When REGE is high,
the device operates in the registered mode. In registered mode, the Address and con-
trol inputs are latched if CLK is held at a high or low logic level. the inputs are stored in
the latch/flip-flop on the rising edge of CLK. REGE is tied to VDD through 10K ohm
Resistor on PCB. So if REGE of module is floating, this module will be operated as reg-
istered mode.

Data input/output

Data inputs/outputs are multiplexed on the same pins.
Check bits for ECC.
Power supply/ground
Power and ground for the input buffers and the core logic.

td, tr = Delay of register (74ALVCF162835)
Notes : 1. In case of module timing, command cycles delayed 1CLK with respect to external input timing at the address and input signal
because of the buffering in register (74ALVCF162835). Therefore, Input/Output signals of read/write function should be
issued 1CLK earlier as compared to Unbuffered DIMMs.
2. DIN is to be issued 1clock after write command in external timing because DIN is issued directly to module.

Notes : 1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time
and then rounding off to the next higher integer.
2. Minimum delay is required to complete write.
3. All parts allow every cycle column address change.
4. In case of row precharge interrupt, auto precharge and read burst stop.
5. In 100MHz and below 100MHz operating conditions, tRDL=1CLK and tDAL=1CLK + 20ns is also supported.
SAMSUNG recommends tRDL=2CLK and tDAL=2CLK + tRP.

Notes :
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.
3. Assumed input rise and fall time (tr & tf) = 1ns.
If tr & tf is longer than 1ns, transient time compensation should be considered,
i.e., [(tr + tf)/2-1]ns should be added to the parameter.

No operation command
(V=Valid, X=Don¢t care, H=Logic high, L=Logic low)
Notes :
1. OP Code : Operand code
A0 ~ A11 & BA0 ~ BA1 : Program keys. (@ MRS)
2. MRS can be issued only at all banks precharge state.
A new command can be issued after 2 clock cycles of MRS.
3. Auto refresh functions are as same as 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 both BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank B is selected.
If both BA0 is "High" and BA1 is "Low" 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.
If A10/AP is "High" at row precharge, BA0 and BA1 is ignored and all banks are selected.
5. During burst read or 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.
6. Burst stop command is valid at every burst length.
7. DQM sampled at positive going edge of a CLK and masks the data-in at the very CLK (Write DQM latency is 0),
but makes Hi-Z state the data-out of 2 CLK cycles after. (Read DQM latency is 2)
