Single +5V (±10%) Supply OperationThe EDI88128CS is
a high speed, high performance, 128Kx8 megabit density
Monolithic CMOS Static RAM.
The device has eight bi-directional input-output lines to provide
simultaneous access to all bits in a word. An automatic power down
feature permits the on-chip circuitry to enter a very low standby
mode and be brought back into operation at a speed equal to the
address access time.
A Low Power version with 2V Data Retention (EDI88128LPS) is
also available for battery back-up opperation. Military product is
available compliant to MIL-PRF-38535.
* 15ns access time is advanced information, contact factory for availability.
This product is subject to change without notice.
