1M x 4 Bit Fast Static
Random Access Memory with
ECL I/O
The MCM101524 is a 4,194,304 bit static random access memory organized
as 1,048,576 words of 4 bits. This circuit is fabricated using high performance
silicon–gate BiCMOS technology. Asynchronous design eliminates the need for
external clocks or timing strobes.
The MCM101524 is available in a 400 mil, 36 lead TAB.
• Fast Access Times: 12, 15 ns
• Equal Address and Chip Select Access Times
• Power Operation: – 195 mA Maximum, Active AC
