M390S2858CT1 SDRAM DIMM
128Mx72 SDRAM DIMM with PLL & Register based on Stacked 128Mx4, 4Banks 8K Ref., 3.3V SDRAMs with SPD
GENERAL DESCRIPTION
The Samsung M390S2858CT1 is a 128M bit x 72 Synchro-
nous Dynamic RAM high density memory module. The Sam-
sung M390S2858CT1 consists of eighteen CMOS Stacked
128Mx4 bit Synchronous DRAMs in two TSOP-II 400mil pack-
ages, three 18-bits Drive ICs for input control signal, one PLL
in 24-pin TSSOP package for clock and one 2K EEPROM in 8-
pin TSSOP package for Serial Presence Detect on a 168-pin
glass-epoxy substrate. Two 0.22uF and one 0.0022uF decou-
pling capacitors are mounted on the printed circuit board in
parallel for each SDRAM. The M390S2858CT1 is a Dual In-
line Memory Module and is intented 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 laten-
cies allows the same device to be useful for a variety of high
bandwidth, high performance memory system applications.

Notes : 1. In case of module timing, command cycles delayed 1CLK with respect to external input timing at the address and input signal
because of the buffering in register (74ALVCF162835). Therefore, Input/Output signals of read/write function should be
issued 1CLK earlier as compared to Unbuffered DIMMs.
2. DIN is to be issued 1clock after write command in external timing because DIN is issued directly to module.

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.
