Abstract
A semiconductor memory device includes a memory cell array, an address control unit and a logic circuit. The memory cell array includes a plurality of banks which are divided into a first bank block and a second bank block. The address control unit accesses the memory cell array. The logic circuit controls the address control unit based on a command and an address signal such that the first and second bank blocks commonly operate in a first operation mode, and the first and second bank blocks individually operate in a second operation mode.
