DESCRIPTION
Front
Side
The Accutek AK5321024N high density memory module is a
CMOS dynamic RAM organized in 1024K x 32 bit words. The module consists of two standard 1 Meg x 16 DRAMs in plastic TSOP
packages. The assembly has 2 drams mounted on the front side of
a printed circuit board in a 72 pad leadless Dual Row Sodim configuration.
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 AK5321024N is identical to two 1Meg x 16
Drams. There are four CAS lines and two RAS lines. On each bank
of 1Meg x 32, independent byte control is accomplished by four CAS
lines. Each seperate CAS line controls one byte of the 1Meg x 16
Dram. A sixteen bit data path can be produced by connecting DQ0
to DQ16, DQ1 to DQ17 etc. and alternately strobing RAS0 with RAS2.
