Features, Applications

The Accutek AK5368192W high density memory module is a CMOS dynamic RAM organized x 36 bit words. The module consists of sixteen standard 4 Meg x 4 DRAMs and eight 4 Meg x 1 DRAMs, each in plastic SOJ packages. The assembly has 14 drams mounted on the front side and 10 drams mounted on the back side of a printed circuit board 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 AK5368192W is identical to sixteen x 4 plus eight x 1 Drams. There are four CAS lines and four RAS lines. On each bank x 36, independent byte control is accomplished by four CAS lines. Each separate CAS line controls two x 4 Drams along with x 1 Dram with data in tied to data out to form a 9 bit byte. Two banks of 36 bits are controlled by the two pairs of RAS lines. An eighteen bit data path can be produced by connecting to DQ19, etc. and alternately strobing RAS0 with RAS1 and RAS2 with RAS3.
