ABSTRACT:
The disclosed flash memory is provided with a majority logic circuit3and shift registers61to63. Three out of the banks2ato2cof the memory respectively include management information areas KAs to store binary management information comprising power supply trimming data and bitline restoration data. During initialization of the flash memory, the majority logic circuit3performs error correction on management information bits retrieved from the management information areas KAs and outputs that information to a trimming/restoration data buffer11, thus providing highly reliable management information very quickly. The shift registers61to63delay a control signal that is output from a control circuit12by a certain period of time before outputting the control signal to sense amplifiers42to44. This delay makes it possible to make the operating currents of the banks2ato2dstart to flow at different times and to suppress a peak current flowing in the flash memory.
