The Samsung M390S2858CTU is a 128M bit x 72 Synchro-
nous Dynamic RAM high density memory module. The Sam-
sung M390S2858CTU consists of eighteen CMOS Stacked
128Mx4 bit Synchronous DRAMs in three TSOP-II 400mil
packages, two 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 0.1uF decoupling capacitors
are mounted on the printed circuit board in parallel for each
SDRAM. The M390S2858CTU is a Dual In-line Memory Mod-
ule 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.
