... SO 2.1 READ mode The M48Z08/ the READ mode whenever W (WRITE enable) is high and E (chip enable) is low. The device architecture allows ripple-through access of data from eight of 65,536 locations in the static storage array. Thus, the unique address specified by the 13 address inputs defines which one of the 8,192 bytes of data accessed. Valid data will be available at the data I/O pins within address access time (t address input signal is stable, providing that the E and G access times are also satisfied ...
