8M-Bit (1Mx8 /512Kx16) CMOS MASK ROM

The KM23V8105D(G) is a fully static mask programmable ROM

fabricated using silicon gate CMOS process technology, and is

organized either as 1,048,576 x 8 bit(byte mode) or as 524,288

x 16 bit(word mode) depending on BHE voltage level.(See

mode selection table)

This device includes PAGE read mode function, page read

mode allows 4 words(or 8 bytes) of data to read fast in the

This device operates with 3.0V or 3.3V power supply, and all

inputs and outputs are TTL compatible.

Because of its asynchronous operation, it requires no external

clock assuring extremely easy operation.

It is suitable for use in program memory of microprocessor, and

data memory, character generator.

The

KM23V8105D

is

packaged

in

a

42-DIP

and

the

KM23V8105DG in a 44-SOP.
