Semiconductor memory device |
| abstract |
Provided is a semiconductor memory device that does not need to save and restore data between a volatile memory device and a nonvolatile memory device in a configuration for stopping and resuming supply of power supply voltage. When a nonvolatile semiconductor memory device is formed, a volatile memory device and a nonvolatile memory device are configured without being separated. Specifically, a semiconductor memory device has a structure in which data is held in a data holding portion connected to a transistor and a capacitor each including an oxide semiconductor in a semiconductor layer. The potential held in the data holding unit is a data potential holding circuit that can output data without leaking charges and the potential held in the data holding unit without leaking charges by capacitive coupling via a capacitive element. It is controlled by a controllable data potential control circuit. [Selection] Figure 1 |
