KM416C254D, KM416V254D
CMOS DRAM
256K x 16Bit CMOS Dynamic RAM with Extended Data Out
DESCRIPTION
This is a family of 262,144 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. Power supply voltage(+5.0V or +3.3V), Access time (-5,-6 or -7), 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 256Kx16 EDO Mode
DRAM family is fabricated using Samsung′s advanced CMOS process to realize high band-width, low power consumption and high reli-
ability. It may be used as graphic memory unit for microcomputer, personal computer and portable machines.
