Adaptive Erase of a Storage Device |
摘要 |
The various implementations described herein include systems, methods and/or devices used to enable adaptive erasure in a storage device. The method includes performing a plurality of memory operations including read operations and respective erase operations on portions of one or more non-volatile memory devices specified by the read operations and respective erase operations, where the respective erase operations are performed using a first set of erase parameters that has been established as a current set of erase parameters prior to performing the respective erase operations. The method includes, in accordance with each erase operation of at least a subset of the respective erase operations, updating one or more erase statistics that correspond to performance of multiple erase operations. The method includes, in accordance with a comparison of the erase statistics with an erasure performance threshold, establishing a second set of erase parameters as the current set of erase parameters. |

1. A method of erasing data in a storage device, the storage device having one or more non-volatile memory devices, the method comprising:
performing a plurality of memory operations including read operations and respective erase operations on portions of the one or more non-volatile memory devices specified by the read operations and respective erase operations, wherein the respective erase operations are performed using a first set of erase parameters that has been established as a current set of erase parameters prior to performing the respective erase operations; in accordance with each erase operation of at least a subset of the respective erase operations, updating one or more erase statistics that correspond to performance of multiple erase operations; and, in accordance with a comparison of the erase statistics with an erasure performance threshold, establishing a second set of erase parameters as the current set of erase parameters. |
