Method and memory device for generating a time estimate

摘要

A method and memory device for generating a time estimate are provided. In one embodiment, a memory device generates a time estimate from time stamps in file system metadata for a plurality of files stored in the memory device and uses the time estimate to perform a time-based activity in the memory device. In another embodiment, a memory device generates a time estimate from time stamps stored in a plurality of files stored in the memory device and uses the time estimate to perform a time-based activity in the memory device. In yet another embodiment, a memory device obtains a plurality of time stamps, selects one or more of the plurality of time stamps based on validity rankings, generates a time estimate from the selected time stamp(s), and uses the time estimate to perform a time-based activity in the memory device.

1. A method for generating a time estimate in a memory device, the method comprising:
performing by a processor in a memory device embedded in a host:
storing in the memory device: (i) a plurality of files and (ii) file system metadata for each of the plurality of files, wherein file system metadata for a given file contains a time stamp associated with that file;generating an estimate of what time it is from the time stamps in the file system metadata for the plurality of files, wherein the memory device does not have a real-time clock; andusing the estimate of what time it is to perform a time-based activity in the memory device.
