M366S1724CT0 PC100 Unbuffered DIMM
Rev. 0.0 April. 2000
The Samsung M366S1724CT0 is a 16M bit x 64 Synchronous
Dynamic RAM high density memory module. The Samsung
M366S1724CT0 consists of eight CMOS 8M x 16 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 M366S1724CT0 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 ~ CA8
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.
WP Write protection WP pin is connected to VSS through 47K Resistor.
When WP is "high", EEPROM Programming will be inhibited and the entire memory will
be write-protected.
VDD/VSS Power supply/ground Power and ground for the input buffers and the core logic.

OPERATING AC PARAMETER
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. For -1H/1L, tRDL=1CLK and tDAL=1CLK+20ns is also supported .
SAMSUNG recommends tRDL=2CLK and tDAL=2CLK + 20ns.
M366S1724CT0 PC100 Unbuffered DIMM

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.

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)
