DESCRIPTION
Front
Side
The Accutek AK5322048N high density memory module is a CMOS
dynamic RAM organized in 2048K x 32 bit words. The module con-
sists of four standard 1 Meg x 16 DRAMs in plastic TSOP packages.
The assembly has 2 drams mounted on each 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 ad-
ditional memory are important.
Back
Side
The operation of the AK5322048A is identical to four 1M x 16
Drams. There are four CAS lines and four RAS lines. On each bank
of 1M x 32, independent byte control is accomplished by four CAS
lines. Each seperate CAS line controls one byte of the 1M x 16
Dram. Two banks of 32 bits are controlled by the two pairs of RAS
lines. A sixteen bit data path can be produced by connecting DQ0 to
DQ16, DQ1 to DQ17 etc. and alternately strobing RAS0 with RAS1
and RAS2 with RAS3.
