Abstract
The semiconductor memory device receives K addresses from first to Kth addresses having at least one bit in common (where K is a natural number; K≧2). Each data block is divided into a plurality of sub data blocks, and a plurality of sense amplifier circuits are provided corresponding to the respective sub data blocks. In each data block, K read data are selected in response to the first address input. Each of the K read data is amplified and output by one of the plurality of sense amplifier circuits sequentially selected in response to each address input.
