Logic block addressing (LBA) configuration method and non-volatile memory device having the same

摘要

A logic block addressing (LBA) configuration method and a non-volatile memory device having the same are provided. The non-volatile memory device determines one of logic zones configured in an LBA table according to the number of booting times. The selected logic zone corresponds to a data zone configured in a physical volume. The non-volatile memory device accesses data stored in the data zone in the selected logic zone. Accordingly, in each boot, the instant disclosure provides the LBA configuration method and the non-volatile memory device having the same, which can show data stored in the different data zones of the physical volume to simplify user operation and avoid the user maliciously destroying or erroneously deleting other data stored in the unused data zones of the physical volume, thereby enhancing the efficiency of the non-volatile memory device executing the multi-booting.

1. A logic block addressing (LBA) configuration method, adapted for a non-volatile memory device, the non-volatile memory device having a switch element to generate a start signal each time a user presses the switch element, the non-volatile memory device having an LBA table corresponding to a physical volume, the LBA table having a plurality of logic zones, and the LBA configuration method comprising: receiving each start signal and counting a number of times that the start signal is received; selecting one of the logic zones according to the number of times and a total amount of the logic zones; and accessing data in the selected logic zone, wherein the selected logic zone corresponds to a data zone of the physical volume and the data is stored in the data zone; wherein the step of selecting one of the logic zones, further comprises a selection function:
vLM=MOD(vPOC/Zone) which is used for selecting one of the logic zones, wherein vLM represents an ordinal of the selected logic zone, vPOC represents the number of times for receiving the start signal, and Zone represents the total amount of the logic zones in the LBA table.
