AK5816384S-60 - Accutek Microcircuit Corporation

DESCRIPTION

The Accutek AK5816384 high density memory module is a CMOS

DRAM organized in 16 Meg x 8 bit words. The assembly consists of

eight 16 Meg x 1 DRAMs in plastic SOJ packages mounted to the

front side of a printed circuit board in 30 pad SIM (leadless) or SIP

(leaded) configuration. The module is only 0.8 inch high (same

height as standard 1 Meg modules), making it ideally suited for ap-

plications with low height restrictions.

The operation of the AK5816384 is identical to eight 16 Meg x 1

DRAMs. The data input is tied to the data output and brought out

separately for each device, with common RAS, CAS and WE con-

trol. This common I/O feature dictates the use of early-write cycles

to prevent contention of D and Q. Since the Write-Enable (WE) sig-

nal must always go low before CAS in a write cycle, Read-Write and

Read-Modify-Write operation is not possible.
