This is a family of 4,194,304 x 16 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 (-50 or -60) are optional features of this
family. All of this family have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh capabilities. This 4Mx16 EDO Mode DRAM
family is fabricated using Samsung
s advanced CMOS process to realize high band-width, low power consumption and high reliability.
