DESCRIPTION
The Accutek AK5321024N high density memory module is a
CMOS dynamic RAM organized in 1024K x 32 bit words. The
module consists of two standard 1 Meg x 16 DRAMs in plastic
TSOPpackages. Theassemblyhas2dramsmountedonthefront
sideofaprintedcircuitboardina72padleadlessDualRowSodim
configuration.
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 AK5321024N is identical to two 1Meg x 16
Drams. Therearefour
