CMOS DRAM
KM44C4003C, KM44C4103C
This is a family of 4,194,304 x 4 bit Quad CAS with Fast Page Mode CMOS DRAMs. Fast Page Mode offers high speed random access
of memory cells within the same row. 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. Four separate CAS pins provide for
seperate I/O operation allowing this device to operate in parity mode.
This 4Mx4 Fast Page Mode Quad CAS DRAM family is fabricated using Samsung
′
s advanced CMOS process to realize high band-
width, low power consumption and high reliability.
