HY51V64400A,HY51V65400A
16Mx4, Fast Page mode
2nd Generation
DESCRIPTION
This family is a 64M bit dynamic RAM organized 16,777,216 x 4-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 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.
