First Claim
Patent Images
1. A method of operating a memory system including a non-volatile storage media, the method comprising:
- reading meta data corresponding to the non-volatile storage media from the non-volatile storage media;
detecting meta data to be updated from the read meta data; and
invalidating storage areas of the non-volatile storage media based on the read meta data and the detected meta data to be updated.

Abstract
In one aspect, meta data corresponding to a non-volatile storage media is read from the non-volatile storage media. Meta data to be updated is detected from the read meta data. Based on the read meta data and the detected meta data to be updated, storage areas of the non-volatile storage media are invalidated.

6. A memory system comprising:
-
a non-volatile storage media; and a controller configured to control the non-volatile storage media, wherein the controller is configured to read meta data corresponding to the non-volatile storage media from the non-volatile storage media, and to invalidate storage areas of the non-volatile storage media based on the read meta data and addresses received from a source external to the memory system. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A computing system comprising:
-
a non-volatile storage media configured to store meta data; a controller configured to control the non-volatile storage media; and a processor configured to read the meta data stored in the non-volatile storage media and to access the non-volatile storage media based on the read meta data, wherein the controller is further configured to read the meta data stored in the non-volatile storage media and to invalidate storage areas of the non-volatile storage media based on the read meta data, while inhibiting invalidation of second storage areas for which a specific time period has not yet passed since the processor last accessed the second storage areas.
