KMM464S424CT1 SDRAM SODIMM
4Mx64 SDRAM SODIMM based on 4Mx16, 4Banks, 4K Refresh, 3.3V Synchronous DRAMs with SPD
GENERAL DESCRIPTION
FEATURE
The Samsung KMM464S424CT1 is a 4M bit x 64 Synchro-
nous Dynamic RAM high density memory module. The Sam-
sung KMM464S424CT1 consists of four CMOS 4M x 16 bit
with 4banks Synchronous DRAMs in TSOP-II 400mil package
and a 2K EEPROM in 8-pin TSSOP package on a 144-pin
glass-epoxy substrate. Three 0.1uF decoupling capacitors are
mounted on the printed circuit board in parallel for each
SDRAM. The KMM464S424CT1 is a Small Outline Dual In-line
Memory Module and is intended for mounting into 144-pin
edge connector 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
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 laten-
cies allows the same device to be useful for a variety of high
bandwidth, high performance memory system applications.
• Serial presence detect with EEPROM

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.

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.

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)
