M381L3313BT0
184pin Unbuffered DDR SDRAM MODULE
M381L3313BT0 DDR SDRAM 184pin DIMM
32Mx72 DDR SDRAM 184pin DIMM based on 16Mx8
GENERAL DESCRIPTION
The Samsung M381L3313BT0 is 32M bit x 72 Double Data
Rate SDRAM high density memory modules based on first
gen. of
128Mb DDR SDRAM respectively. The Samsung
M381L3313BT0 consists of eighteen CMOS 16M x 8 bit with
4banks Double Data Rate SDRAMs in 66pin TSOP-II(400mil)
packages mounted on a 184pin glass-epoxy substrate. Four
0.1uF decoupling capacitors are mounted on the printed circuit
board in parallel for each DDR SDRAM. The M381L3313BT0
is Dual In-line Memory Modules and intended for mounting into
184pin edge connector sockets.
Synchronous design allows precise cycle control with the use
of system clock. Data I/O transactions are possible on both
edges of DQS. Range of operating frequencies, programmable
latencies and burst lengths allow the same device to be useful
for a variety of high bandwidth, high performance memory sys-
tem applications.
