HY51V(S)64403HG/HGL
16M x 4Bit EDO DRAM
PRELIMINARY
DESCRIPTION
This familiy is a 64Mbit dynamic RAM organized 16,777,216 x 4 bit configuration with Extended Data Out
mode CMOS DRAMs. Extended data out mode is a kind of page mode which is useful for the read opera-
tion. The advanced circuit and process allow this device to achieve high performance and low power dissi-
pation. Features are access time(45ns or 50ns) and refresh cycle(8K ref ) and power consumption
(Normal or low power with self refresh).
Advanced CMOS process as well as circuit techniques for wide operating margins allow this device to
achieve high speed access and high reliability
