ABSTRACT:
A reference potential generator is constituted of two signal lines 21 and 22; a charge supplier to supply charge to signal lines 21 and 22; connectors 24a and 24b connecting the charge supplier 23 and two signal lines 21 and 22 in order to supply charge to the two signal lines; and a connector 25 connecting two signal lines 21 and 22 together by the second control signal, and two signal lines are disconnected after the potentials of the two signal lines determined by the supplied charge and each of load capacitances of signal lines are averaged. A semiconductor memory device of the invention incorporating the above reference potential generator generating an exact reference potential, is able to amplify and output the potential difference between the reference potential and the potential of data readout in the bit line, and by this, "1" or "0" of readout data can be precisely determined.
