A semiconductor integrated circuit device easily finds whether an error is located in an X decoder or a Y decoder. Circuit generating full cyclic sequences (36) and (38) are disposed which correspond to an X decoder (32) and a Y decoder (33), respectively, of a memory circuit (21). A specific state detection circuit (37) detects a specific address state of the circuit generating full cyclic sequence (36) so that one of an X address and a Y address is changed only after the other one of the X address and the Y address is thoroughly changed. Since when the error was created is known, which one of the X decoder and the Y decoder is responsible for the error is easily found. |
