Abstract
An address generator circuit (21A) includes a shift register (28) for storing therein address data (AD) to be outputted. A plurality of memory circuits which are equal in one of the numbers of bits of X and Y addresses for specifying rows or columns of memory cell arrays and different in the other number, apply data to scan paths so that less significant bits of the addresses having the same number of bits are stored in a position closer to an input terminal. An XOR gate (27A) in the address generator circuit (21A) generates write data (DI) for writing RAMs (31, 32) from data (X0, Y0) stored in predetermined registers of the shift register (28).
