Abstract
A semiconductor memory includes a memory cell for storing data; a bit-line pair to be charged to an electric potential corresponding to the data stored in the memory cell; a data-line pair to be electrically connected to the bit-line pair; and a main amplifier for amplifying an electric potential difference of the data-line pair and outputting a signal corresponding to the data. The main amplifier restrains itself from outputting the signal corresponding to the data until the electric potential difference of the data-line pair becomes higher than a predetermined value.
