K4E660411B,K4E640411B

CMOS DRAM

16M x 4bit CMOS Dynamic RAM with Extended Data Out

DESCRIPTION

This is a family of 16,777,216 x 4 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, -50 or -60), 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 capa-

bilities. This 16Mx4 EDO Mode DRAM family is fabricated using Samsung′s advanced CMOS process to realize high band-width, low

power consumption and high reliability.
