STORING DATA IN STORAGE DEVICES

摘要

Technologies are generally described to store data in a storage device that includes an array of analog memory cells. Example storage devices described herein may include one or more of an interface, and/or a processor coupled to the interface. The processor may be configured to store, via the interface, data as first analog values in a first group of memory cells in the array. Second analog values may be read, via the interface, from the first group of memory cells in which the data were stored. A first distortion representative of a difference between the first analog values and the second analog values may be then verified. Further, the second analog values may be encoded by use of an error correction code (ECC) to generate third analog values. The third analog values may be stored, via the interface, in a second group of memory cells in the array.

1. A method to store data in a storage device that includes an array of analog memory cells, the method comprising:
storing data as first analog values in a first group of memory cells in the array; reading second analog values from the first group of memory cells in which the data were stored; verifying a first distortion representative of a difference between the first analog values and the second analog values; encoding the second analog values using an error correction code (ECC) to generate third analog values; storing the third analog values in a second group of memory cells in the array; reading fourth analog values from the second group of memory cells in which the third analog values were stored; and verifying a second distortion representative of a difference between the third analog values and the fourth analog values.
