Abstract
A nonvolatile memory may include a count data region provided in a memory region which is counted up according to an updating data and a fiat number of times managing region provided in a memory region which manages the full-counted number of times of the count data region. The nonvolatile memory may include a second number of times managing region which manages the full-counted number of times of the first number of times managing region. The nonvolatile memory is preferably utilized in an electronic device such as a card reader to detect the expiration of service lifetimes of the structural components of the electronic device.
