Overview
MICROCIRCUIT CORPORATION DESCRIPTION The Accutek AK594096A high density memory module is a CMOS random access memory organized in 4 Meg x 9 bit words.
The assembly consists of nine standard 4 Meg x 1 DRAMs in plastic leaded chip carriers (SOJ) mounted on the front side of a printed circuit board.
The module can be configured as a leadless 30 pad SIM or a leaded 30 pin SIP.
The module is only 0.
800 inches high (same height as a standard 1 Meg module), making it ideally suited for applications with low height restrictions.
The operation of the AK594096A is identical to nine 4 Meg x 1 DRAMs.
For the lower eight bits data input is tied to the data output and brought out separately for each device, with common RAS, CAS 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.
