ABSTRACT:
A life parameter generator generates life parameters related to the life of a nonvolatile memory device by using parameters related to allowable capacity for memory defect and occurrence capacity for memory defect. The life parameters are stored in a life parameter storing block of a nonvolatile memory. An access device reads and displays the stored life parameters. Thus, the user can precisely know the life of the nonvolatile memory device or the moment when a device having a built in nonvolatile memory such as a portable audio becomes unusable.
