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
packages mounted on the front 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-
ditional memory are important.
The operation of the AK5321024BW is identical to eight 1 Meg x 4
Drams. There are four
of 1M x 32, independent byte control is accomplished by four
lines. Each seperate
Dram.
· 1,048,576 x 32 bit organization
· 72 pad Single In-Line Module
· Standard with gold fingers, solder or tin plating optional
· CAS-before-RAS, RAS-only or hidden refresh
· Operating free air temperature 0
· Single 5 Volt Power Supply
· 1024 Refresh Cycles, 16 mSEC
· Available in Fast Page Mode or EDO
