1 / 2 page DESCRIPTION The Accutek AK5324096W high density memory module is a CMOS Dynamic RAM organized in 4096K x 32 bit words. The mod- ule consists of eight standard 4 Meg x 4 DRAMs in plastic SOJ pack- ages mounted on the front surface of a printed circuit board with a low profile height of only 0.875" in a 72 pin leadless SIM configura- tion. 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 AK5324096W is identical to eight 4 Meg x 4 drams. There are four CAS lines and two RAS lines. Independent byte control is accomplished by four CAS lines. Each separate CAS line controls two of the 4 Meg 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 DQ0 to DQ16,DQ1 to DQ17, etc. and alternately strobing RAS0 with RAS2.
