A reset control apparatus, which carries out reset control in response to an external reset signal, includes a count start signal generating unit for producing a count start signal in response to the external reset signal, a counter for starting counting in response to the count start signal, and a reset signal generating unit for outputting an internal reset signal in response to the external reset signal, and for halting the output of the internal reset signal while the counter counts a predetermined count value. The reset control apparatus can solve a problem of a conventional reset control apparatus in that when the pulse width of the external reset signal passing through a noise canceler is narrower than the period of the clock signal, it cannot sample the signal, and hence cannot generate the internal reset signal.
