DESCRIPTION

The Accutek AK532256W high density memory module is a CMOS

dynamic RAM organized in 256K x 32 bit words. The module con-

sists of eight standard 256K x 4 DRAMs in plastic SOJ packages.

The assembly has eight drams mounted on the front side of a

printed circuit board in a 72 pad leadless SIM configuration.

The operation of the AK532256W is identical to eight 256K x 4

DRAMs. There are four CAS lines and two RAS lines. Independent

byte control is accomplished by four CAS lines. Each seperate CAS

line controls two 256K 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 DQ1 to DQ17,DQ2 to DQ18 and alter-

nately strobing RAS0 with RAS2.
