AK5328192W

MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK5328192W high density memory module is a CMOS dynamic RAM organized in 8192K x 32 bit words. The module consists of sixteen standard 4 Meg x 4 DRAMs in plastic SOJ packages. The assembly has eight 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. The operation of the AK5328192W is identical to sixteen 4M x 4 Drams. There are four CAS lines and four RAS lines. On each bank of 4M x 32, independent byte control is accomplished by four CAS lines. Each separate CAS line controls two 4M x 4 Drams to form an 8 bit byte. 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.
