512K x 8 Bit Static Random  
Access Memory  
The MCM6946/SCM6946 is a 4,194,304–bit static random access memory or-  
ganizedas 524,288 words of 8 bits. Static design eliminates the need for external  
clocks or timing strobes.  
The MCM6946/SCM6946 is equipped with chip enable (E) and output enable  
(G) pins, allowing for greater system flexibility and eliminating bus contention  
problems. Either input, when high, will force the outputs into high impedance.
