1 / 21 page KM48C8004B, KM48C8104B 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), 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. This 8Mx8 EDO Mode DRAM family is fabricated using Samsung ′s advanced CMOS process to realize high band-width, low power con- sumption and high reliability. • Part Identification - KM48C8004B(5.0V, 8K Ref.) - KM48C8104B(5.0V, 4K Ref.) • Extended Data Out Mode operation • CAS-before-RAS refresh capability • RAS-only and Hidden refresh capability • Fast parallel test mode capability • TTL(5.0V) compatible inputs and outputs • Early Write or output enable controlled write • JEDEC Standard pinout • Available in Plastic SOJ and TSOP(II) packages • +5.0V ±10% power supply Control Clocks RAS CAS W Vcc Vss A0~A12 (A0~A11)*1 A0~A9 (A0~A10)*1 Memory Array 8,388,608 x 8 Cells SAMSUNG ELECTRONICS CO., LTD. reserves the right to change products and specifications without notice. 8M x 8bit CMOS Dynamic RAM with Extended Data Out DESCRIPTION FEATURES FUNCTIONAL BLOCK DIAGRAM Note) *1 : 4K Refresh • Refresh Cycles Part NO.
