CMOS DRAM
K4F660411C, K4F640411C
This is a family of 16,777,216 x 4 bit Fast Page Mode CMOS DRAMs. Fast Page Mode offers high speed random access of memory
cells within the same row. Refresh cycle(4K Ref. or 8K Ref.), access time(-50 or -60), package type(SOJ or TSOP-II) are optional fea-
tures of this family. All of this family have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh capabilities. This 16Mx4 Fast
Page Mode DRAM family is fabricated using Samsung
′s advanced CMOS process to realize high band-width, low power consumption
and high reliability.
