SOJ
TSOPII
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 (tPC) to occur without the output data going invalid. This elimination of CAS output control allows pipeline Read.
