AC23V8000
1MX8 BIT
CMOS MASK ROM
Description
The AC23V8000 high performance read only memory is organized 1,048,576 x 8 bit (byte mode) and has
an access time of 70/100/120ns. The low power feature allows the battery operation. The large size of
8M bit memory density is ideal for charactergenerator, data or program memory in micro-processor
application. The AC23V8000 is provided as die form in waffle pack tray.
