DESCRIPTION

The Accutek AK5324096W high density memory module is a

CMOS Dynamic RAM organized in 4096K x 32 bit words. The mod-

ule consists of eight standard 4 Meg x 4 DRAMs in plastic SOJ pack-

ages 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 configura-

tion. 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 AK5324096W is identical to eight 4 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 4 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
