Overview
MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK5916384S high density memory module is a CMOS random access memory organized in 16 Meg x 9 bit words.
The assembly consists of nine 16 Meg x 1 DRAMs in plastic SOJ packages mounted on the front side of a printed circuit board in 30 pad SIM (leadless) or 30 pin 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.
The operation of the AK5916384 is identical to nine 16 Meg x 1 dynamic RAMs.
For the lower eight bits data input is tied to 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.
For the ninth bit, the data input (D9) and the data output (Q9) pins are brought out separately and controlled by a separate PCAS for that bit.
Bit nine is generally used for parity.
