Abstract:
A semiconductor memory device includes a first memory region, a second memory region suitable for storing the same data as the first memory region, and a ray detection circuit suitable for detecting an incident ray to the first memory region, wherein a data stored in the second memory region is copied into the first memory region when the incident ray is detected.
