Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention, but do not limit the invention to only some, but not all embodiments.
Referring to FIG. 1, a flow chart of an error handling method is shown, applied to a non-volatile memory.
In the embodiment of the present invention, through a lot of research, the inventor finds that NandFlash Read Error may occur when an FTL (flash translation layer) performs an internal data moving operation, where the NandFlash Read Error refers to an uncorrectable Error occurring when the FTL reads NandFlash data. In a normal situation, when the FTL performs an internal data transfer operation, it will not detect whether the read Page data is erroneous, so that the read erroneous data is directly transferred to the good Block without any error record, so that the erroneous data cannot be identified.
In view of the above, in the embodiment of the present invention, when a data moving operation is performed in response to a garbage collection instruction, if a Page data read error occurs in a Block, an error flag is set for the Page data in which the error occurs, and the Page data in which the error occurs and a corresponding error flag are written into a new Page of the preset Block, when data reading or other operations need to be performed in the preset Block, the Page data in which the error occurs during garbage collection can be conveniently identified according to the error flag.
The method specifically comprises the following steps:
step 101: and receiving a garbage collection instruction.
In the embodiment of the invention, the storage space of the nonvolatile memory can be required to be sorted through garbage collection in consideration of the fact that the storage space of the nonvolatile memory cannot be well utilized due to the fact that the storage space is fragmented by some scattered storage and invalid data along with the use of the nonvolatile memory.
In the specific application, the received garbage collection instruction can indicate that garbage collection is needed, when the garbage collection is carried out, invalid data in a Block of a nonvolatile memory can be erased, scattered valid data are moved to a preset Block, and the preset Block can be good blocks with continuous storage spaces.
Step 102: responding to the garbage collection instruction, and carrying out data moving operation; wherein the data transfer operation is: and moving the effective data dispersed in the Block of the nonvolatile memory to a preset Block.
In the embodiment of the present invention, as described above, in response to the garbage collection instruction, the FTL may perform a data transfer operation to transfer the effective data dispersed in the Block of the nonvolatile memory to the preset Block.
Step 103: and if a Page data reading error occurs in the Block during the data transfer operation, setting an error mark for the Page data with the error.
In the embodiment of the invention, if a Page data reading error in the Block occurs during the data moving operation, an error flag is set for the Page data with the error. For example, if the maximum number of bits that the FTL can read is 24 bits, and one Page data includes 25 bits, only 24 bits can be read during reading, and a read error occurs, so that an error flag may be set for the Page data in which the error occurs. In a specific application, the mark can be stored in a metadata space which is used for self management in a nonvolatile memory, and excessive occupation of a storage space which can be operated by a user is avoided.
Step 104: and writing the Page data with the error and the corresponding error mark into a new Page of the preset Block.
In the embodiment of the present invention, since the FTL is not authorized to discard data and the like when used for data transfer, even if an error occurs during data reading, the Page data with the error and the corresponding error flag need to be written into a new Page of the preset Block, so that when other modules process the Page data, the Page data with the error can be identified.
As a preferable mode of the embodiment of the present invention, referring to fig. 2, the method further includes:
step 105: a data read instruction is received.
Step 106: and responding to the data reading instruction, and reading the data in the preset Block.
Step 107: and if Page data provided with an error mark is detected in the reading process, reporting the error mark to Host.
Step 108: and when a invalidation instruction of the Host is received, invalidating the Page data with the error flag.
Step 109: and processing the Page data with the error flag as valid data when the valid instruction of the Host is received.
In the embodiment of the invention, after receiving a data reading instruction, the FTL can read the Page data in the preset Block, and if the Page data with the error flag is detected in the fetching process, the error flag is reported to the Host, and the Host is used for determining that the Page data corresponding to the error flag is invalid or is treated as effective data according to actual application. In an actual application, assuming that Page data corresponding to an error marker is only a small part of data in a certain section of video data, processing the Page data as effective data can not affect the video, and sending an effective instruction, and processing the Page data provided with the error marker as effective data under the condition of receiving the effective instruction of Host; suitably, the Host can also decide to invalidate the Page data corresponding to the error flag, and then can send an invalidation instruction, and under the condition that the invalidation instruction of the Host is received, the Page data with the error flag is invalidated.
In summary, in the embodiment of the present invention, when a data moving operation is performed in response to a garbage collection instruction, if a Page data read error occurs in a Block, an error flag is set for the Page data with the error, and the Page data with the error and the corresponding error flag are written into a new Page of the preset Block, when data reading or other operations are required to be performed on the preset Block, the Page data with the error during garbage collection can be conveniently identified according to the error flag.
