64K X 16 BIT HIGH SPEED CMOS SRAM
General Description
The A616316 is a high speed 1,048,576-bit static random access memory organized as 65,536 words by 16 bits and operates on supply voltage 5V. It is built using AMIC's high performance CMOS process. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures. The chip enable input is provided for POWER-DOWN, to disable the device. Two byte enable inputs and an output enable input are included for easy interfacing. Data retention is guaranteed at a power supply voltage as low as 3V.

Notes: 1. tAS is measured from the address valid to the beginning of Write. 2. A Write occurs during the overlap (tWP, tBW) of a low CE , WE and ( HB and, or LB ). 3. tWR is measured from the earliest of CE or WE or ( HB and, or LB ) going high to the end of the Write cycle. 4. OE level is high or low. 5. Transition is measured 500mV from steady state. This parameter is sampled and not 100% tested.
