ABSTRACT:
The memory device memorizes a number corresponding to a plurality of digits, for example, a unit phone number using a first memory array. A desired number is obtained by selecting a Y address. A readout operation is executed by inputting whole data selected by a Y address to a second memory array at once and outputting data sequentially from the second memory array by one digit. A write operation is executed by inputting data sequentially to the second memory array by one digit and outputting data from the second memory array to the first memory array at once.
