Abstract
A method for reading data for a semiconductor memory device including steps of selecting a plurality of memory locations on which data are stored by word-lines and bit-lines, and reading the data from the bit-lines is provided, which comprises the steps of precharging the word-line by activating the first precharge signal; precharging the bit-line by activating a second precharge signal after a lapse of predetermined time since the first precharge signal has been activated; selecting a predetermined memory location in response to address signals; and reading data stored on the memory location from the bit-line by inactivating the first and second precharge signals.
