M366S3323DTS SDRAM DIMM
32Mx64 SDRAM DIMM based on 16Mx8, 4Banks, 4K Refresh, 3.3V Synchronous DRAMs with SPD
GENERAL DESCRIPTION
FEATURE
The Samsung M366S3323DTS is a 32M bit x 64 Synchronous
Dynamic RAM high density memory module. The Samsung
M366S3323DTS consists of sixteen CMOS 16M x 8 bit with
4banks Synchronous DRAMs in TSOP-II 400mil package and a
2K EEPROM in 8-pin TSSOP package on a 168-pin glass-epoxy
substrate. Two 0.1uF decoupling capacitors are mounted on the
printed circuit board in parallel for each SDRAM.
The M366S3323DTS is a Dual In-line Memory Module and is
intended for mounting into 168-pin edge connector sockets.
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 allows
the same device to be useful for a variety of high bandwidth, high
performance memory system applications.

PIN CONFIGURATION DESCRIPTION
Pin
Name
Input Function
CLK
System clock
Active on the positive going edge to sample all inputs.
CS
Chip select
Disables or enables device operation by masking or enabling all inputs except
CLK, CKE and DQM.
CKE
Clock enable
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 should be enabled 1CLK+tSS prior to valid command.
A0 ~ A11
Address
Row/column addresses are multiplexed on the same pins.
Row address : RA0 ~ RA11, Column address : CA0 ~ CA9
BA0 ~ BA1
Bank select address
Selects bank to be activated during row address latch time.
Selects bank for read/write during column address latch time.
RAS
Row address strobe
Latches row addresses on the positive going edge of the CLK with RAS low.
Enables row access & precharge.
CAS
Column address strobe
Latches column addresses on the positive going edge of the CLK with CAS low.
Enables column access.
WE
Write enable
Enables write operation and row precharge.
Latches data in starting from CAS, WE active.
DQM0 ~ 7
Data input/output mask
Makes data output Hi-Z, tSHZ after the clock and masks the output.
Blocks data input when DQM active. (Byte masking)
DQ0 ~ 63
Data input/output
Data inputs/outputs are multiplexed on the same pins.
VDD/VSS
Power supply/ground
Power and ground for the input buffers and the core logic.

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.

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)
