CMOS Mask Programmable Read only Memory
Rev. 0.0
Dec. 1, 1995
Description
The HN624316 is a 16-Mbit CMOS mask-programmable ROM organized either as 1048576 words by 16
bits or as 2097152 words by 8 bits. Realizing low power consumption, this memory is allowed for
battery operation. And a high speed access of 120/150 ns is the most suitable to the system using a high
speed microcomputer by 16 bits as 8086 and 68000 e.t.c..
