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 applica-

tions 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.
