HY514404A

1Mx4, Extended Data Out mode

DESCRIPTION

This family is a 4M bit dynamic RAM organized 1,048,576 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 operation. The circuit and process

design allow this device to achieve high performance and low power dissipation. Optional features are access time(50, 60

or 70ns) and package type(SOJ, TSOP-II) 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.
