16,777,216 Word by 8 Bit CMOS
Dynamic Random Access Memory
Front View
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 applications with low height restrictions.

30-Pin SIP
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 control. This common I/O feature dictates the use of early-write cycles
to prevent contention of D and Q. Since the Write-Enable (WE) signal must always go low before CAS in a write cycle, Read-Write and
Read-Modify-Write operation is not possible.
