DESCRIPTION
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 DQ0 to DQ18, DQ1 to DQ19,
etc. and alternately strobing RAS0 with RAS2.
