PROBLEM TO BE SOLVED: To reduce current consumption in a standby at least. SOLUTION: Information showing the presence of a short-circuit failure is programmed in a memory block (MKB) through the fuse program circuits (100, 104). According to the fuse program information and a mode instruction signal (RFVPP), on a specific mode, a correlation between a block selection signal and corresponding bit line separation instruction signals (BL1<K>R, BL1<K>L) is switched by circuits (102, 106) for generating bit line separation instruction signals. Thus, on the specific operation mode, a memory block in which a leakage current path is present is separated from a corresponding sense amplifier band (SAB<K>). COPYRIGHT: (C)2004,JPO&NCIPI
