PROBLEM TO BE SOLVED: To provide a memory device in which the power consumption required for pre-charge is less. SOLUTION: Before a processor 400 performs memory access, a bit line to be pre-charged is predicted by a bit line variation predicting circuit 120 based on variation of an address signal 10, pre-charge is performed for only a bit line predicted by an output signal 121 of the bit line variation predicting circuit, the power consumption is reduced without delaying access time to a memory by performing no pre-charge for the other bit lines. |
