Abstract
A semiconductor memory device comprising a memory cell array includes a plurality of memory cells. The device includes: a predecoder for dividing a plurality of bits of an address signal into at least two bit strings so as to decode each bit string and output predecoded results of each bit string in parallel; a series of shift registers, each shift register being provided for a respective bit string, receiving the predecoded results of the corresponding bit string as shift data, shifting the received shift data, thereby generating and outputting predecoded signal bits; and a main decoder for decoding the predecoded signal bits output from the plurality of shift registers and selecting a memory cell in the memory cell array in accordance with the results of the decoding.
