The Accutek AK5364096W high density memory module is a
CMOS Dynamic RAM organized in 4096K x 36 bit words. The mod-
ule consists of eight standard 4 Meg x 4 DRAMs and four 4 Meg x 1
DRAMs in plastic SOJ packages. The 4 Meg x 4 DRAMs are
mounted on the front surface and the 4 Meg x 1 parity DRAMs are
mounted on the back surface of a printed circuit board with a low
profile height of only 0.875" in a 72 pin 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 AK5364096W is identical to eight 4Meg x 4 plus
four 4Meg x 1 DRAMs. There are four CAS lines and two RAS lines.
Independent byte control is accomplished by four CAS lines. Each
separate CAS line controls two 4Meg x 4 DRAMs, along with a 4Meg
x 1 DRAM with data in tied to data out to form a 9 bit byte. The bank
of 36 bits is controlled by the two RAS lines. An eighteen bit data
path can be produced by connecting DQ
etc. and alternately strobing RAS
