摘要：A memory module comprises a plurality of semiconductor memory devices eachcomprising a mode register set (MRS) circuit configured to generate an enable signal

corresponding to an error mode of the semiconductor memory device in response to anMRS command received from a command decoder, and an address buffer configured tostore a predetermined address signal, to receive an address signal and correspondingdata from an external device, and to compare the address signal received with thepredetermined address signal in response to the enable signal. As a consequence ofdetermining that the address signal received from the external device is the same as thepredetermined address signal stored in the address buffer, data different from thecorresponding data received from the external device is written to a memory cellcorresponding to the predetermined address signal.
