CMOS DRAM
This is a family of 2,097,152 x 8 bit Extended Data Out CMOS DRAMs. Extended Data Out Mode offers high speed random access of
memory cells within the same row, so called Hyper Page Mode. Power supply voltage (+5.0V or +3.3V), refresh cycle (2K Ref. or 4K
Ref.), access time (-50 or -60), power consumption(Normal or Low power) and 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. Furthermore, Self-refresh
operation is available in L-version. This 2Mx8 EDO Mode DRAM family is fabricated using Samsung
′
s advanced CMOS process to real-
ize high band-width, low power consumption and high reliability. It may be used as graphic memory unit for microcomputer and personal
computer.
