ABSTRACT:
Apparatus and method for transferring segmented memory between memory units determines a need for memory transfer and searches a memory unit segment by segment until a valid data record is found. This valid data record is conveyed to another memory unit via the asynchronous mode. If a valid data records is not found within a predetermined amount of time, a message identifying the memory segment last searched is conveyed. If no remaining valid data records are found, a message with no information is conveyed. Priority is given to asynchronous messages.
