2,097,152 Word by 36 Bit CMOS
Dynamic Random Access Memory
DESCRIPTION
The Accutek AK5362048BW high density memory module is a
CMOS dynamic RAM organized in 2048K x 36 bit words. The module consists of four standard 1 Meg x 16 bits DRAMs and two 1 Meg
x 4 bit Quad CAS DRAM in plastic SOJ packages. The assembly
has 3 DRAMs mounted on each side of a printed circuit board in a 72
pad leadless SIM configuration.
1
This configuration allows socket-mounting of large quantities of
memory in applications where high density and ease of inserting additional memory are important.
The operation of the AK5362048BW is identical to sixteen 1 Meg x 4
plus eight 1 Meg x 1 DRAMs. There are four CAS lines and two RAS
lines. On each bank of 1 Meg x 36, independent byte control is accomplished by four CAS lines. Each seperate CAS line controls one
byte of the 1 Meg x 16 plus a parity bit in the QUAD CAS DRAM.
