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
