Specifications of KM44C4104CK-6

Case
SOJ
This is a family of 4.194,304 x 4 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 (-5 or -6), 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 4Mx4 EDO DRAM family is fabricated using Samsung s advanced CMOS process to realize high band-width, low power consump-
tion and high reliability. It may be used as main memory unit for high level computer, microcomputer and personal computer.
