DESCRIPTION
The Accutek AK5321024W high density memory module is a
CMOS Dynamic RAM organized in 1024K x 32 bit words. The
moduleconsistsofeightstandard1Megx4DRAMsinplasticSOJ
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. Therearefour

lines. Independent
bytecontrolisaccomplishedbyfour
CAS
lines. Eachseparate
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 DQ
