DESCRIPTION
The Accutek AK5328192BW high density memory module is a
CMOS dynamic RAM organized in 8,192K x 32 bit words. The mod-
ule consists of four standard 4 Meg x 16 bits DRAMs in plastic
TSOP packages. The assembly has two DRAMs mounted on each
side of a printed circuit board in 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 ad-
ditional memory are important.
The operation of the AK5328192BW is identical to sixteen 4 Meg x 4
DRAMs. There are four CAS lines and four RAS lines. On each
bank of 4 Meg x 32, independent byte control is accomplished by
four CAS lines. Each seperate CAS line controls one byte of the
4 Meg x 16 Dram.
