General Description Minimum standby power is drawn by this device when CE is at a high level, independent of the other input levels. Data retention is guaranteed at a power supply voltage as low as 2.0V. The A625308A is a low operating current 262,144-bit static random access memory organized as 32,768 words by 8 bits and operates on a voltage from 4.5V to 5.5V. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures.

A Write occurs during the overlap (tWP) of a low CE and a low WE . tWR is measured form the earliest of CE or WE going high to the end of the Write cycle. If the CE low transition occurs simultaneously with the WE low transition or after the WE transition, outputs remain in a high impedance state. 5. tCW is measured from the later of CE going low to the end of Write. 6.
