OPERATION METHOD FOR SEMICONDUCTOR MEMORY DEVICE AND OPERATION METHOD FOR SEMICONDUCTOR MEMORY MODULE INCLUDING A PLURALITY OF SEMICONDUCTOR MEMORY DEVICE

摘要

The present invention relates to a semiconductor memory device capable of performing a repair operation on its own, and a semiconductor memory module including the same, the method comprising: a method of operating a semiconductor memory device including a fuse array for storing at least one repair address; Additionally latching a repair address having an address value not stored in the fuse array in response to the active command in the operation mode, and inputting a repair entry control code externally applied in response to the first column command in the repair operation mode Whether to perform the operation is determined according to the receiving step and the value of the repair entry control code, and the latching repair address is ruptured to the fuse array in the latching in response to the second column command, and is applied after the second column command. Repair in response to precharge command Escape from the operating mode.
