Dynamic Random Access Memory  
DESCRIPTION  
Front View  
30-Pin SIM  
The Accutek AK581024 high density memory modules is a random  
access memory organized in 1 Meg x 8 bit words. The assembly  
consists 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 stan-  
dard 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 al-  
ways go low before CAS in a write cycle, Read-Write and  
Read-Modify-Write operation is not possible.
