ABSTRACT:
An image memory comprises a random access memory, a serial access memory including a main register and a preregister, a data transfer section for carrying out data transfer between the random access memory and the serial access memory, and a designation section for designating an address of serial access. The data transfer section serves to transfer data from the random access memory to the main register of the serial access memory through the preregister. Furthermore, a serial access to the serial access memory is made on the basis of an address designated by the designation means. Thus, a transfer system defined as a hidden transfer for carrying out data transfer only between the random access memory and the preregister is set as a technique for relaxing the restriction on the transfer timings. This technique permits the serial access memory to be used with the divided or split segments having arbitrary lengths, respectively.
