HY51V64164,HY51V65164

4Mx16, Extended Data Out mode

1st Generation

DESCRIPTION

This family is a 64M bit dynamic RAM organized 4,194,304 x 16-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 operation. The circuit and process

design allow this device to achieve high performance and low power dissipation. Optional features are access time(60 or

70ns) and refresh cycle(8K ref. or 4K ref.) and power consumption (Normal or Low power with self refresh). Hyundai鈥檚

advanced circuit design and process technology allow this device to achieve high bandwidth, low power consumption and

high reliability.
