Description

This is a family of 2,097,152 x 8 bit Fast Page Mode CMOS DRAMs KM48V2000B. Fast Page Mode KM48V2000B offers high speed random access of memory cells within the same row. Power supply voltage (+5.0V or +3.3V), refresh cycle (2K Ref. or 4K Ref.), 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 CASbefore- RAS refresh, RAS-only refresh and Hidden refresh capabilities. Furthermore, Self-refresh operation is available in L-version. This 2Mx8 Fast Page Mode DRAM family KM48V2000B is fabricated using Samsung's advanced CMOS process to realize high band-width, low power consumption and high reliability.

KM48V2000B may be used as graphic memory unit for microcomputer, personal computer and portable machines.
