ABSTRACT:
A semiconductor memory device includes load circuits of column sense amplifiers arranged correspondingly to Y-addresses (global bit line pairs), respectively. A plurality of memory blocks commonly use the load circuit. Each memory block includes input circuits of the column sense amplifiers for the bit line pairs, respectively. Each input circuit is activated in response to the corresponding block select signal. In response to the potential on the corresponding bit line pair, a potential difference occurs on the corresponding global bit line pair. The load circuit increases this potential difference.
