PC66 SDRAM MODULE
The Samsung KMM366S104CTL is a 1M bit x 64 Synchronous
Dynamic RAM high density memory module. The Samsung
KMM366S104CTL consists of four CMOS 1M x 16 bit Synchro-
nous DRAMs in TSOP-II 400mil package and a 1K or 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 parellel for each SDRAM. The
KMM366S104CTL 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.

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, BA 0 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 assoiated bank can be issued at t RP 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)
