KM48V8004C,KM48V8104C CMOS DRAM
This is a family of 8,388,608 x 8 bit Extended Data Out Mode CMOS DRAMs. Extended Data Out 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. Furthermore, Self-refresh operation is available in L-version. This 8Mx8 EDO Mode DRAM family is fabricated using Sam­sungs advanced CMOS process to realize high band-width, low power consumption and high reliability.

ABSOLUTE MAXIMUM RATINGS
* Permanent device damage may occur if "ABSOLUTE MAXIMUM RATINGS" are exceeded. Functional operation should be restricted to
the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

*Note :
ICC1, ICC3, ICC4 and ICC6 are dependent on output loading and cycle rates. Specified values are obtained with the output open. ICC is specified as an average current. In ICC1, ICC3 and ICC6, address can be changed maximum once while RAS=VIL. In ICC4, address can be changed maximum once within one EDO mode cycle time, tHPC.
