CMOS DRAM
This is a family of 8,388,608 x 8 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 (-45, -5 or -6), power consumption(Normal or Low power) are
optional features of this family. All of this family have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh capabilities. Fur-
thermore, Self-refresh operation is available in L-version. This 8Mx8 Fast Page Mode DRAM family is fabricated using Samsung
′
s
advanced CMOS process to realize high band-width, low power consumption and high reliability.
