Accutek Microcircuit Corporation AK5361024BW 1,048,576 Word by 36 Bit CMOS Dynamic Random Access Memory DESCRIPTION The Accutek AK5361024BW high density memory module is a CMOS dynamic RAM organized in 1024K x 36 bit words. The module consists of two standard 1 Meg x 16 bits DRAMs and one 1 Meg x 4 bit Quad CAS DRAM in plastic SOJ packages. The assembly has 3 DRAMs mounted on the front side of a printed circuit board in a 72 pad leadless SIM configuration. 1 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 AK5361024BW is identical to eight 1 Meg x 4 plus four 1 Meg x 1 DRAMs. There are four CAS lines and two RAS lines. Independent byte control is accomplished by four CAS lines. Each seperate CAS line controls one byte of the 1 Meg x 16 plus a parity bit in the QUAD CAS DRAM.
