ABSTRACT:
A semiconductor memory device includes a pair of read address terminals which supplies first and second read addresses for outputting stored at a selected memory cell to one of a pair of bit lines, and a selector which selects one of the bit lines corresponding to whether a present reading is for the first read address or for the second read address, and which outputs a data read in the selected bit line to an output terminal. Accordingly, the semiconductor memory device can set a frequency of a signal applied to a precharge signal input terminal to a value which is lower than a conventional semiconductor memory device, and can improve the speed at which the data is read.
