DESCRIPTION
The M28F101 FLASH Memory is a non-volatile
memory which may be erased electrically at the
chip level and programmed byte-by-byte. It is or-
ganised as 128K bytes of 8 bits. It uses a command
register architecture to select the operating modes
and thus provides a simple microprocessor inter-
face. The M28F101 FLASH Memory is suitable for
applications where the memory has to be repro-
grammed in the equipment. The access time of
70ns makes the device suitable for use in high
speed microprocessor systems.
