DESCRIPTION
The Accutek AK5364096W high density memory module is a
CMOSDynamicRAMorganizedin4096Kx36bitwords. Themod-
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
memoryinapplicationswherehighdensityandeaseofinsertingad-
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.

bank of 36 bits is controlled by the two
