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
path can be produced by connecting DQ0 to DQ16, DQ1 to DQ17
etc. and alternately strobing RAS0 with RAS2.
