SEMICONDUCTOR DEVICE, MEMORY SYSTEM AND SEMICONDUCTOR MEMORY DEVICE

A semiconductor device includes a transmission and reception circuit and a control circuit. The transmission and reception circuit transmits and receives a signal to and from a semiconductor memory device. The control circuit acquires threshold voltage distribution information of a memory element connected to a word line for read disturb detection to which a second voltage higher than a first voltage applied to an adjacent word line adjacent to a read target word line during a read operation is applied and determines an influence of read disturb based on the threshold voltage distribution information.
