Abstract
A portable storage device comprises a nonvolatile memory, a nonvolatile memory area, an indicator, and a controller. When machine-readable data stored in the nonvolatile memory is altered, the controller automatically calculates utilization information of the nonvolatile memory and stores the same in the nonvolatile memory area. The indicator is coupled to the nonvolatile memory, nonvolatile memory area, and the controller and displays the utilization information accordingly.
Claims15
A portable storage device, comprising:
- a non-volatile memory storing machine-readable data;
- a non-volatile memory area;
- a controller coupled to the memory and the memory area, when data stored therein changes, automatically calculating utilization information of the memory and storing the utilization information in the memory area;
- and
- an indicator coupled to the controller, the memory, and the memory area, displaying the utilization information stored in the memory area.
