DESCRIPTION
The Accutek AK5816384 high density memory module is a CMOS
DRAMorganizedin16Megx8bitwords. Theassemblyconsistsof
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-
nalmustalwaysgolowbeforeCASinawritecycle,Read-Writeand
Read-Modify-Write operation is not possible.
