STMicroelectronics M68Z128
The M68Z128 is a 1 Mbit (1,048,576 bit) CMOS SRAM, organized as 131,072 words by 8 bits. The device features fully static operation requiring no external clocks or timing strobes, with equal address access and cycle times. It requires a single 5V ±10% supply, and all inputs and outputs are TTL compatible.DESCRIPTION

Except for the rating "Operating Temperature Range", stresses above those listed in the Table "ABSOLUTE MAXIMUM RATINGS
" may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.
