SM5322000TP
8MByte (2M x 32) CMOS DRAM Module - Thin Profile
General Description
The SM5322000TP is a high performance, 8-megabyte
dynamic RAM module organized as 2M words by 32 bits,
in a thin, 72-pin, leadless, single-in-line memory module
(SIMM) package.
The module utilizes sixteen CMOS 1M x 4 dynamic RAMs
in surface mount (TSOP) package on an epoxy laminate
substrate. Each device is accompanied by a decoupling
capacitor for improved noise immunity.
Control lines are provided such that byte control is possible.
