Abstract
A method of providing an exposure temperature includes generating reference information indicating relationships between an exposure condition and a retention value, where the exposure condition include an exposure temperature and an exposure time of a nonvolatile memory device and the retention value indicates retention characteristic of the nonvolatile memory device, before a power-off time point when the nonvolatile memory device is powered-off, performing a monitoring program operation to write monitoring data in target memory cells included in the nonvolatile memory device, after a power-on time point when the nonvolatile memory device is powered on, generating a measured retention value by performing a monitoring read operation to read data from the target memory cells, and estimating, based on the reference information, a measured exposure temperature corresponding to the measured retention value and a measured exposure time between the power-off time point and the power-on time point.
