ABSTRACT:
A semiconductor memory device divided into a number of main blocks each main block having a number of subblocks selects a single main block and enables the subblocks of the selected main block, so as to reduce the power consumptions. The semiconductor memory device includes a block selector for selecting one of the main blocks in response to row address signals, a number of first boost circuits for selecting the subblocks of the selected main block in response to the row address signals, and a number of second boost circuits adapted to be disabled in response to the row address signals.
