AK532256AW

MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK532256AW high density memory module is a CMOS dynamic RAM organized in 265K x 32 bit words. The module consists of two standard 256K x 16 bits DRAMs in plastic SOJ packages. The assembly has 2 DRAMs mounted on the front 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 additional memory are important. The operation of the AK532256AW is identical to eight 256K x 4 Drams. There are four CAS lines and two RAS lines. On each bank of 256K x 32, independent byte control is accomplished by four CAS lines. Each seperate CAS line controls one byte of the 256K x 16 Dram.
