DESCRIPTION
The Accutek AK532256AW high density memory module is a
CMOS dynamic RAM organized in 265K x 32 bit words. The mod-
ule consists of two standard 256K x 16 bits DRAMs in plastic SOJ
packages. The assembly has 2 DRAMs mounted on the front side
of a printed circuit board in a 72 pad leadless SIM configuration.
This configuration allows socket-mounting of large quantities of
memoryinapplicationswherehighdensityandeaseofinsertingad-
ditional memory are important.
The operation of the AK532256AW is identical to eight 256K x 4
Drams. Therearefour
