DRAM MODULE
GENERAL DESCRIPTION
KMM5321200C2W/C2WG with Fast Page Mode
1M x 32 DRAM SIMM using 1Mx16, 1K Refresh, 5V
The Samsung KMM5321200C2W is a 1Mx32bits Dynamic
RAM
KMM5321200C2W consists of two CMOS 1Mx16bits DRAMs
in 42-pin SOJ packages mounted on a 72-pin glass-epoxy
substrate. A 0.1 or 0.22uF decoupling capacitor is mounted
on the printed circuit board for each DRAM. The
KMM5321200C2W is a Single In-line Memory Module with
edge connections and is intended for mounting into 72 pin
edge connector sockets.
