摘要：
A nonvolatile memory system includes a nonvolatile memory device including a plurality of memory cells, and a memory controller. The memory controller is configured to count a clock to generate a current time, program dummy data at predetermined memory cells among the plurality of memory cells at a power-off state, detect a charge loss of the predetermined memory cells when a power-on state occurs after the power-off state, and restore the current time based on the detected charge loss.
