Abstract:
A semiconductor memory device includes a reference voltage generator for generating a plurality of reference voltages each having different voltage levels in response to a self refresh enable control signal, and a voltage comparator for generating a result signal that controls a self refresh operation cycle by comparing each of the plurality of reference voltages with a temperature information voltage that represents an internal temperature of an integrated circuit.
