Description
The Hitachi HM5116405 Series, HM5117405 Series are CMOS dynamic RAMs organized 4,194,304-word
× 4-bit. They employ the most advanced CMOS technology for high performance and low power. The
HM5116405 Series, HM5117405 Series offer Extended Data Out (EDO) Page Mode as a high speed
access mode. They have package variations of standard 26-pin plastic SOJ and standard 26-pin plastic
TSOP II.
