PC66 SDRAM MODULE
KMM366S403CTL SDRAM DIMM
4Mx64 SDRAM DIMM based on 2Mx8, 4K Refresh, 3.3V Synchronous DRAMs with SPD
GENERAL DESCRIPTION
FEATURE
The Samsung KMM366S403CTL is a 4M bit x 64 Synchronous
Dynamic RAM high density memory module. The Samsung
KMM366S403CTL consists of sixteen CMOS 2M x 8 bit Synchronous DRAMs in TSOP-II 400mil package and a 2K
EEPROM in 8-pin TSSOP package on a 168-pin glass-epoxy
substrate. Two 0.33uF decoupling capacitors are mounted on
the printed circuit board in parallel for each SDRAM. The
KMM366S403CTL 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.

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.

(V=Valid, X=Don′t care, H=Logic high, L=Logic low)
Notes :1. OP Code : Operand code
A0 ~ A10/AP, BA0 : Program keys. (@ MRS)
2. MRS can be issued only at both banks precharge state.
A new command can be issued after 2 clock cycle 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 both banks precharge state.
4. BA0 : Bank select address.
If "Low" at read, write, row active and precharge, bank A is selected.
If "High" at read, write, row active and precharge, bank B is selected.
If A10/AP is "High" at row precharge, BA0 is ignored and both 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 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)
