SEMICONDUCTOR TECHNICAL DATA  
MCM6926A  
Advance Information  
128K x 8 Bit Fast Static Random  
Access Memory  
The MCM6926A is a 1,048,576 bit static random access memory organized  
as 131,072 words of 8 bits. Static design eliminates the need for external clocks  
or timing strobes.  
WJ PACKAGE  
400 MIL SOJ  
CASE 857A–02  
Output enable (G) is a special control feature that provides increased system  
flexibility and eliminates bus contention problems.  
This device meets JEDEC standards for functionality and revolutionary pinout,  
and is available in a 400 mil plastic small–outline J–leaded package.
