Dynamic Random Access Memory
DESCRIPTION
The Accutek AK5328192W high density memory module is a
CMOS dynamic RAM organized in 8192K x 32 bit words. The mod-
ule consists of sixteen standard 4 Meg x 4 DRAMs in plastic SOJ
packages. The assembly has eight drams mounted on each side of
a printed circuit board in a 72 pad leadless SIM configuration.
+
This configuration allows socket-mounting of large quantities of
memory in applications where high density and ease of inserting ad-
+
1
ditional memory are important.
72
The operation of the AK5328192W is identical to sixteen 4M x 4
Drams. There are four CAS lines and four RAS lines. On each bank
of 4M x 32, independent byte control is accomplished by four CAS
lines. Each separate CAS line controls two 4M x 4 Drams to form an
8 bit byte. Two banks of 32 bits are controlled by the two pairs of
RAS lines. A sixteen bit data path can be produced by connecting
DQ₀ to DQ₁₆, DQ₁ to DQ₁₇, etc. and alternately strobing RAS₀ with
RAS₁ and RAS₂ with RAS₃.
