Dynamic Random Access Memory

ACCUTEK

MICROCIRCUIT CORPORATION

DESCRIPTION

The Accutek AK5361024W high density memory module is a

CMOS Dynamic RAM organized in 1024K x 36 bit words. The mod-

ule consists of eight standard 1 Meg x 4 DRAMsin plastic SOJ pack-

ages mounted on the front side of a printed circuit board and four 1

Meg x 1 DRAMs in plastic SOJ packages mounted on the back side

of a printed circuit board with a low profile height of only 0.875 inch

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 AK5361024W is identical to eight 1 Meg x 4

plus four 1 Meg 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 1Meg x 4 DRAMs, along with a

1 Meg 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 DQ₀to DQ₁₈, DQ₁to DQ₁₉,

etc. and alternately strobing RAS₀with RAS₂.
