A refresh signal generation circuit is provided to change constantly a refresh period according to a change of temperature. A refresh signal generation circuit includes a control signal generation unit(100), an oscillator(200), and a refresh signal generation unit(300). The control signal generation unit generates control signals(Vp,Vn) by dividing a supply voltage(Vcc). The oscillator generates a pulse signal(OSC) having a controllable period in response to a control signal. The refresh signal generation unit generates a refresh signal(SREFq) in response to the pulse signal. |
