HM5164165F Series
HM5165165F Series
64M EDO DRAM (4-Mword × 16-bit)
8k refresh/4k refresh
ADE-203-1058B(Z)
Rev. 2.0
Nov. 30, 1999
Description
The Hitachi HM5164165F Series, HM5165165F Series are 64M-bit dynamic RAMs organized as 4,194,304-
word × 16-bit. They have realized high performance and low power by employing CMOS process technology.
HM5164165F Series, HM5165165F Series offer Extended Data Out (EDO) Page Mode as a high speed
access mode. They have the package variations of standard 50-pin plastic SOJ and standerd 50-pin plastic
TSOPII
