CMOS DRAM
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), power consumption(Normal
or Low power) are optional features of this family. All of this family have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh
capabilities. Furthermore, Self-refresh operation is available in L-version. This 8Mx8 EDO Mode DRAM family is fabricated using Sam-
sung
′
s advanced CMOS process to realize high band-width, low power consumption and high reliability.
