Semiconductor MSM538001E
1,048,576-Word x 8-Bit MASKROM
DESCRIPTION
The OKI MSM538001E is a high-speed silicon gate CMOS Mask ROM with 1,048,576word x 8-bit capacity. The MSM538001C operates on a single 5.0V power supply and is TTL compatible. The chip's asynchronous I/O requires no external clock assuring easy operation. A power-down mode provides low power dissipation when the chip is not selected. The CE and OE pins are provided as control signals that permit three-stated output allowing easy memory expansion on a system bus. The MSM538001E is suited for use as large capacity fixed memory for microcomputers and data terminals.
