MCM6949  
1M x 4 Bit Static Random  
Access Memory  
The MCM6949 is a 4,194,304–bit static random access memory organized as  
1,048,576 words of 4 bits. Static design eliminates the need for external clocks  
or timing strobes.  
YJ PACKAGE  
400 MIL SOJ  
CASE 857A–02  
The MCM6949 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.  
TheMCM6949isavailableina400mil, 32–leadsurface–mountSOJpackage.  
PIN NAMES  
Single 3.3 V – 5%, + 10% Power Supply  
Fast Access Time: 8/10/12/15 ns
