A memory chip unit includes a pad electrode including first and second portions, and a memory cell array. A prober includes a probe card and a movement mechanism. The probe card includes a probe electrode to be in contact with the pad electrode, and a memory controller electrically coupled to the probe electrode and executes reading and writing on the memory cell array. The movement mechanism executes a first operation that brings the probe electrode into contact with the first portion and does not bring the probe electrode into contact with the second portion, and a second operation that does not bring the probe electrode into contact with the first portion and brings the probe electrode into contact with the second portion.
