DESCRIPTION
The Accutek AK5321024BW high density memory module is a
CMOS dynamic RAM organized in 1024K x 32 bit words. The mod-
ule consists of two standard 1 Meg x 16 bits DRAMs in plastic SOJ
packagesmountedonthefrontsideofaprintedcircuitboardina72
pad leadless SIM configuration.
This configuration allows socket-mounting of large quantities of
memoryinapplicationswherehighdensityandeaseofinsertingad-
ditional memory are important.
The operation of the AK5321024BW is identical to eight 1 Meg x 4
Drams. Therearefour

of 1M x 32, independent byte control is accomplished by four
CAS
lines. Each seperate
CAS
line controls one byte of the 1 Meg x 16
Dram.
