Abstract
A semiconductor device includes a first memory block, a second memory block, a first refresh control block for generating a first block control signal and a second block control signal in response to a refresh pulse signal, a second refresh control block for generating a first refresh control pulse signal and a second refresh control pulse signal corresponding to a first refresh operation section of the first memory block and a second refresh operation section of the second memory block, respectively, in response to the refresh pulse signal and the first and second block control signals, and a third refresh control block for controlling the first and second memory blocks so that a first refresh operation of the first memory block and a second refresh operation of the second memory block are discontinuously performed in response to the first and second refresh control pulse signals.
