High Speed 4 Megabit EEPROM Multichip Module
General Description
The ACT–E128K32 is a high speed, 4 megabit, CMOS EEPROM multichip module MCM designed for full temperature range military, space, or high reliability applications. The MCM can be organized as a 256K x 16 bits or 512K x 8 bits device and is input and output CMOS and TTL compatible. Writing is executed when the write enable WE and chip enable CE inputs are low and output enable OE is high. Reading is accomplished when WE is high and CE and OE are both low. Access times grades of 120, 140, 150, 200, 250 & 300ns are standard.
