Abstract
An electronic device includes a count signal generation circuit configured to increase one of the values of a weak cell count signal and an active count signal by comparing a weak cell address with an adjacent address generated from a row address, when an active operation is performed. The electronic device also includes a target refresh control circuit configured to latch the adjacent address based on the values of the weak cell count signal and the active count signal and to output the latched adjacent address as a target address for a refresh operation based on a target refresh signal.
