Description

Accutek Microcircuit AK581024AS 1 Meg x 8, 30 Pin SIM Module, 2-Chip Version Simple Type: Memory Module The Accutek AK581024 high density memory modules is a random access memory organized in 1 Meg x 8 bit words. The assemblyconsists of two 1 Meg x 4 DRAMs in surface mount packages mounted to a printed circuit board. The module can be configured as a leadless 30 pad SIMM or a leaded 30 pin SIP. This packaging approach provides a better than 6 to 1 density increase over standard DIP packaging. The operation of the AK581024 is identical to two 1 Meg x 4 DRAMs. The data input/output is brought out separately for each 1 Meg x 4 device, with common RAS, CAS and WE control. The OE pins are tied to Vss which 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. Download the datasheet (PDF)
