GENERAL DESCRIPTION
M11L416256 series randomly accessed solid state memory, organized 262,144 bits device. offers Extended Data-Output 3.3V( 10%) single power supply. Access time (-35) self-refresh package type (SOJ, TSOP optional features this family. these family have before -only refresh Hidden refresh capabilities. access modes supported this device: Byte access Word access. only leave other staying high will result BYTE access. WORD access happens when CASL CASH used.
CASL transiting during READ WRITE cycle will output input data into lower byte (IO0~IO7), CASH transiting will output input data into upper byte (IO8~15).
