PROBLEM TO BE SOLVED: To provide an address circuit whose required circuit space is reduced. SOLUTION: The circuit is provided with a high speed shift register 43 and a low speed shift register 41 and the high speed shift register 43 and the low speed shift register 41 are connected by a selection logic circuit 45. Moreover, a timing logic 47 is connected electrically to the high speed shift register 43 and the low speed shift register 41. Thus, while random accessing of a degree is attained, the required circuit space is reduced.
