1,048,576 Word by 32 Bit CMOS
Dynamic Random Access Memory
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.
Back
Side
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.
