GENERAL DESCRIPTION
The M11B1644/M11L1644 series is a randomly accessed solid state memory, organized as 4,194,304 x 4 bits device. It
offers Extended Data-Output access mode. Single power supply (5V
10%, 3.3V
10%), access time (-45,-50,-60), self-
refresh function and package type (SOJ, TSOP II) are optional features of this family. All these family have CAS - before -
RAS
, RAS -only refresh and Hidden refresh.
The primary advantage of EDO is the availability of data-out even after CAS returns high. EDO allows CAS precharge
time (t
PC
) to occur without the output data going invalid. This elimination of CAS output control allows pipeline Read.

Permanent device damage may occur if "Absolute
Maximum Ratings" are exceeded. This is a stress rating
only, and functional operation of the device above those
conditions indicated in the operational sections of this
specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect reliability.
