8Mx8, Fast Page mode

2nd Generation

DESCRIPTION

This family is a 64M bit dynamic RAM organized 8,388,608 x 8-bit configuration with Fast Page mode CMOS DRAMs.

Fast Page mode offers high speed of random access memory within the same row. 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 package(SOJ or TSOP-ll) 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.
