| 发明名称 | Random number processing apparatus and random number processing method | ||
| 摘要 | A random number processing apparatus includes a memory cell and a control circuitry. The memory cell has a characteristic in which a resistance value reversibly shifts between a plurality of resistance value ranges in accordance with an electric signal applied. The control circuitry generates random number data on the basis of a plurality of items of resistance value information obtained, at a plurality of different times, from the memory cell whose resistance value is in a certain resistance value range of the plurality of resistance value ranges. The resistance value of the memory cell randomly changes over time while the resistance value is within the certain resistance value range. | ||

| 主权项 | 1. A random number processing apparatus comprising: a memory cell in which a resistance value reversibly shifts between a plurality of resistance value ranges in accordance with an electric signal applied and in which the resistance value randomly changes over time while the resistance value is within a certain resistance value range, at least part of which is included in the plurality of resistance value ranges; and control circuitry that generates random number data on the basis of a plurality of items of resistance value information obtained, at a plurality of different times, from the memory cell whose resistance value is within the certain resistance value range. | ||
