DESCRIPTION
AK532256W 262,144 Word by 32 Bit CMOS Dynamic Random Access Memory

The Accutek AK532256W high density memory module is a CMOS dynamic RAM organized x 32 bit words. The module consists of eight standard x 4 DRAMs in plastic SOJ packages. The assembly has eight drams mounted on the front side of a printed circuit board a 72 pad leadless SIM configuration. The operation of the AK532256W is identical to eight x 4 DRAMs. There are four CAS lines and two RAS lines. Independent byte control is accomplished by four CAS lines. Each seperate CAS line controls two 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 to DQ18 and alternately strobing RAS0 with RAS2.
