REFRESHING OF MEMORY BLOCKS USING ADAPTIVE READ DISTURB THRESHOLD |
| 摘要 |
A method includes storing data in a memory that includes multiple memory blocks. A level of distortion that affects a given memory block of the memory is estimated. An adaptive read disturb threshold is set for the given memory block as a function of the estimated level of distortion. Upon detecting that a number of read operations performed in the given memory block exceeds the read disturb threshold, the data stored in the memory block is copied to an alternative storage location. |

1. A method, comprising:
storing data in a memory that includes multiple memory blocks; estimating a level of distortion that affects a given memory block of the memory; setting an adaptive read disturb threshold for the given memory block as a function of the estimated level of distortion; and upon detecting that a number of read operations performed in the given memory block exceeds the read disturb threshold, copying the data stored in the memory block to an alternative storage location.
