HY51V64164A,HY51V65164A
4Mx16, Extended Data Out mode
2nd 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(50 or
60ns) and refresh cycle(8K ref. or 4K ref.) and power consumption (Normal or Low power with self refresh). Hyundai’s
advanced circuit design and process technology allow this device to achieve high bandwidth, low power consumption and
high reliability.
