Semiconductor device and memory module including the semiconductor device

Abstract

A semiconductor device includes a counter configured to count a refresh signal and output a counting signal. The semiconductor device may include a mode control circuit configured to receive a first mode signal for controlling a refresh cycle and a second mode signal for constantly controlling a refresh cycle, in correspondence to error correction code information, configured to output an advanced refresh signal in which the refresh cycle is adjusted, by controlling the counting signal depending on the first mode signal, and configured to output a smart refresh signal which has a constant refresh cycle, in correspondence to the second mode signal. The semiconductor device may include a refresh control circuit configured to output a bank address for performing a refresh operation that is set in correspondence to the advanced refresh signal and the smart refresh signal, to a bank.
