M53230400CW0/CB0 & M53230410CW0/CB0 EDO Mode 4M x 32 DRAM SIMM using 4Mx4, 4K/2K Refresh, 5V
GENERAL DESCRIPTION
The Samsung M5323040(1)0C is a 4Mx32bits Dynamic RAM high density memory module. The Samsung M5323040(1)0C consists of eight CMOS 4Mx4bits DRAMs in 24-pin SOJ package 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 M5323040(1)0C is a Single In-line Memory Module with edge connections and is intended for mounting into 72 pin edge connector sockets.
