Description
The Hitachi HN58V256A and HN58V257A are electrically erasable and programmable ROMs organized as
32768-word
×
8-bit. They have realized high speed, low power consumption and high reliability by
employing advanced MNOS memory technology and CMOS process and circuitry technology. They also
have a 64-byte page programming function to make their write operations faster.
