NT511740D5J
16MEG : x4
CMOS with Extended Data Out
DESCRIPTION
This is a family of 4,194,304 x 4 bit Extended Data Out CMOS DRAMs. Extended Data Out Mode offers high speed
random access of memory cells within the same row, so called Hyper Page Mode. Power supply voltage (+5.0V ), refresh
cycle (2K Ref), access time (-5 or -6), power consumption (Normal or Low power) and package type (SOJ) are optional
features of this family.
All of this family have

RAS
-only refresh and Hidden refresh capabilities. Furthermore,
Self-refresh operation is available in L-version. This 4Mx4 EDO Mode DRAM family is fabricated using NANYA’s advanced
CMOS process to realize high bandwidth, low power consumption and high reliability.
It may be used as main memory unit for microcomputer, high level computer and personal computer .

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.
