CMOS DRAM

8M x 8bit CMOS Dynamic RAM with Extended Data Out

DESCRIPTION

This is a family of 8,388,608 x 8 bit Extended Data Out Mode CMOS DRAMs. Extended Data Out Mode offers high speed random

access of memory cells within the same row. Refresh cycle(4K Ref. or 8K Ref.), access time (-45, -5 or -6), package type (SOJ or TSOP-

II) are optional features of this family. All of this family have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh capabilities.

This 8Mx8 EDO Mode DRAM family is fabricated using Samsung¢s advanced CMOS process to realize high band-width, low power con-

sumption and high reliability.
