Overview

MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK5321024W high density memory module is a CMOS Dynamic RAM organized in 1024K x 32 bit words.
The module consists of eight standard 1 Meg x 4 DRAMs in plastic SOJ packages.
The assembly has eight drams mounted on the front surface of a printed circuit board with a low profile height of only 0.
875" in a 72 pin leadless SIM configuration.
This configuration allows socket-mounting of large quantities of memory in applications where high density and ease of inserting additional memory are important.
The operation of the AK5321024W is identical to eight 1 Meg x 4 DRAMs.
There are four CAS lines and two RAS lines.
Independent byte control is accomplished by four CAS lines.
Each separate CAS line controls two of the 1 Meg x 4 DRAMs to form an 8 bit byte.
The bank of 32 bits is controlled by the two RAS lines.
A sixteen bit data path can be produced by connecting DQ0 to DQ16, DQ1 to DQ17, etc.
and alternately strobing RAS0 with RAS2.
