Description

technical field [0001] Various embodiments relate generally to semiconductor devices and semiconductor memory devices, and more particularly, to semiconductor devices and semiconductor memory devices related to performing sudden power off operations and power on reset operations. Background technique [0002] Generally, semiconductor devices perform circuit operations by using internal power supply voltages generated based on external power supply voltages. Similarly, semiconductor memory devices including volatile memory devices and nonvolatile memory devices also perform circuit operations by using internal power supply voltages generated based on external power supply voltages. [0003] Furthermore, a volatile memory device is advantageous in that a data processing speed, which is a speed for storing external data therein or outputting internal data to the outside, is high. However, a disadvantage of a volatile memory device is that it needs to continuously receive an ex...
