The Accutek AK5368192W high density memory module is a

CMOS dynamic RAM organized in 8192K x 36 bit words. The mod-

ule consists of sixteen standard 4 Meg x 4 DRAMs and eight 4 Meg

x 1 DRAMs, each in plastic SOJ packages. The assembly has 14

drams mounted on the front side and 10 drams mounted on the back

side of a printed circuit board in a 72 pad leadless SIM configuration.

This configuration allows socket-mounting of large quantities of

memory in applications where high density and ease of inserting ad-

ditional memory are important.

The operation of the AK5368192W is identical to sixteen 4M x 4 plus

eight 4M x 1 Drams. There are four CAS lines and four RAS lines.

On each bank of 4M x 36, independent byte control is accomplished

by four CAS lines. Each separate CAS line controls two 4M x 4

Drams along with a 4M x 1 Dram with data in tied to data out to form a

9 bit byte. Two banks of 36 bits are controlled by the two pairs of

RAS lines. An eighteen bit data path can be produced by connect-

ing DQ

with RAS
