Embodiment Construction

[0030] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them.

[0031] figure 1 It is a schematic structural diagram of a non-volatile storage medium provided in this application. The non-volatile storage medium can be, but not limited to: Nand flash memory, NOR flash memory. see figure 1 , the non-volatile storage medium includes: a controller 101 and a storage unit 102 .

[0032] Wherein, the controller 101 controls the storage unit 102 to perform data reading, writing, erasing, and recycling of data pages. The number of storage units 102 is at least one.

[0033] The following is an example of implementing ...

Abstract

The invention provides a nonvolatile storage medium data processing method and a nonvolatile storage medium in the technical field of storage. The method comprises the steps of obtaining a first operation parameter value of a storage unit; wherein the first operation parameter value represents data read-write performance of the storage unit; when the first operation parameter value meets a recovery condition, recovering the valid data page in a failure data block; and not recovering the valid data page when the first operation parameter value does not meet the recovery condition; when the recovery of the valid data page is executed and the recovery condition is not met, pausing the recovery of the valid data page or not performing the recovery of the valid data page is not carried out, sothat the bus bandwidth is provided for data reading and writing, and data reading and writing efficiency is improved.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a nonvolatile storage medium data processing method and the nonvolatile storage medium. Background technique [0002] During the use of the solid-state hard disk, some data may become invalid, and the invalid data occupies the data blocks of the solid-state hard disk, resulting in a waste of solid-state hard disk space. Usually, a Garbage Collection (GC) strategy is adopted, which is used to sort out the valid data pages in the data blocks to be reclaimed, transfer the valid data pages to free positions, and form new data blocks, and the invalid data pages are not transferred. It remains in the data block to be recycled. After all the valid data pages are transferred, the data blocks to be reclaimed are erased as a whole to complete the GC work. [0003] Currently, the GC strategy adopts an idle time trigger mechanism, that is, when it detects that the host has no data...
