DESCRIPTION Accutek Microcircuit Corporation AK5328192BW 8,388,608 Word by 32 Bit CMOS Dynamic Random Access Memory The Accutek AK5328192BW high density memory module is a CMOS dynamic RAM organized in 8,192K x 32 bit words. The module consists of four standard 4 Meg x 16 bits DRAMs in plastic TSOP packages. The assembly has two DRAMs mounted on each 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. + + 1 72 The operation of the AK5328192BW is identical to sixteen 4 Meg x 4 DRAMs. There are four CAS lines and four RAS lines. On each bank of 4 Meg x 32, independent byte control is accomplished by four CAS lines. Each seperate CAS line controls one byte of the 4 Meg x 16 Dram.
