Abstract
A nonvolatile memory element including a resistance variable element configured to reversibly change between a low-resistance state and a high-resistance state in response to electric signals with different polarities; and a current controlling element configured such that when a current flowing when a voltage whose absolute value is a first value which is larger than 0 and smaller than a predetermined voltage value and whose polarity is a first polarity is applied is a first current and a current flowing when a voltage whose absolute value is the first value and whose polarity is a second polarity is applied is a second current, the first current is higher than the second current, and the resistance variable element is connected with the current controlling element such that the first polarity voltage is applied to the current controlling element when the resistance variable element changes from the low-resistance to the high-resistance state.
