Dynamic Random Access Memory  
DESCRIPTION  
Front View  
30-Pin SIM  
The Accutek AK591024 high density memory modules is a random  
access memory organized in 1 Meg x 9 bit words. The assembly  
consists of two 1 Meg x 4 and one 1 Meg x 1 DRAMs in surface  
mount packages 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. This packaging approach provides a better than 6 to 1  
density increase over standard DIP packaging.

30-Pin SIP  
The operation of the AK591024 is identical to two 1 Meg x 4 plus one  
1 Meg x 1 DRAMs. For the lower eight bits, the data input is tied to  
data output and 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 conten-  
tion 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  
data output (Q9) pins are brought out separately and controlled by a  
separate PCAS for that bit. Bit nine is generally used for parity.
