ABSTRACT:
A video storage device capable of realizing a still image-holding mode. The storage device has a serial input-output configuration. A serial input register is connected with a memory array via a transfer gate circuit which selectively permits transfer of data from the serial input register to the memory array. An address counter is connected with the serial input register. In the still image-holding mode, the transfer gate circuit is disabled, and the memory array is accessed in response to counting operation of the address counter. The address counter acts also as a refreshing counter for refreshing the memory array.
