... The M48Z35AV is a non-volatile pin and function equivalent to any JEDEC standard SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed ...

... SO 2.1 READ mode The M48Z35AV is in the READ mode whenever W (WRITE enable) is high, E (chip enable) is low. The device architecture allows ripple-through access of data from eight of 264,144 locations in the static storage array. Thus, the unique address specified by the 15 address inputs defines which one of the 32,768 bytes of data accessed. Valid data will be available at the data I/O pins within address access time (t signal is stable, providing that the E and G access times are also satisfied ...
