CMOS DRAM

4M x 1Bit CMOS Dynamic RAM with Fast Page Mode

DESCRIPTION

This is a family of 4,194,304 x 1bit Fast Page Mode CMOS DRAMs. Fast Page Mode offers high speed random access of memory cells

within the same row. Power supply voltage (+5V or +3.3V), 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 CAS-before-RAS refresh, RAS-only refresh and

Hidden refresh capabilities. Furthermore, self-refresh operation is available in Low power version.

This 4Mx1 Fast Page Mode DRAM family is fabricated using Samsung¢s advanced CMOS process to realize high band-width, low power

consumption and high reliability. It may be used as main memory for main frames and mini computers, personal computer and high per-

formance microprocessor systems.
