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.
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.
• Single 3.3 V Power Supply
• Fully Static — No Clock or Timing Strobes Necessary
• All Inputs and Outputs Are TTL Compatible
• Three State Outputs
• Fast Access Times: 8, 10, 12, 15 ns
• Center Power and I/O Pins for Reduced Noise
• Fully 3.3 V BiCMOS
