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.
