64K X 16 BIT LOW VOLTAGE CMOS SRAM
General Description
The A62S6316H is a low operating current 1,048,576-bit static random access memory organized as 65,536 words by 16 bits and operates on low power supply voltage from 2.7V to 3.3V. 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, device enable. 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 2V.
