GENERAL DESCRIPTION
The M11L416256 series is a randomly accessed solid state memory, organized as 262,144 x 16 bits device. It offers
Extended Data-Output , 3.3V( ± 10%) single power supply. Access time (-35) , self-refresh 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
capabilities.
Two access modes are supported by this device: Byte access and Word access. Use only one of the two CAS and leave
the other staying high will result in a BYTE access. WORD access happens when two CAS ( CASL , CASH ) are used.
CASL transiting low during READ or WRITE cycle will output or input data into the lower byte (IO0~IO7), and CASH
transiting low will output or input data into the upper byte (IO8~15).
