sram

Hi, do FRAMs need their CE(bar) signal pulsed at every r/w access, unlike SRAMs? Example: Infineon FM18W08 Parallel 5.0V which can replace the 62256 SRAM / 28c256 EEPROM. What if If I do this: 8085 A15 to input to 1 of the 74HC04 inverters and to CE(bar) (pin 20) of FRAM 1. and output of the...
