AK5322048N

MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK5322048N high density memory module is a CMOS dynamic RAM organized in 2048K x 32 bit words. The module consists of four standard 1 Meg x 16 DRAMs in plastic TSOP packages. The assembly has 2 drams mounted on each side of a printed circuit board in a 72 pad leadless Dual Row Sodim 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 AK5322048A is identical to four 1M x 16 Drams. There are four CAS lines and four RAS lines. On each bank of 1M x 32, independent byte control is accomplished by four CAS lines. Each seperate CAS line controls one byte of the 1M x 16 Dram. 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.
