Description
Renesas Technology
's
HN58C256A and HN58C257A 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.
