SEMICONDUCTOR MEMORY DEVICE, OPERATING METHOD THEREOF, AND DATA STORAGE DEVICE INCLUDING THE SAME

摘要

A semiconductor memory device includes a setting information area suitable for storing setting information necessary for driving of memory cells, a control logic suitable for loading the setting information stored in the setting information area on a content-addressable memory (CAM) block, a CAM state information storage block suitable for storing information on whether the setting information loaded on the CAM block is changed, wherein when a reloading operation of the setting information stored in the setting information area on the CAM block is requested, the control logic selectively performs the reloading operation based on the information stored the CAM state information storage block.
