Problems solved by technology

However, due to the limited number of Pages included in each block, when a PairBlock is full or a complete step is not written, before continuing to write data, you can first switch to another set of PairBlocks and erase the data stored in the PairBlock , if there is an error in erasing, it will cause the PairBlock to be unable to read and write normally or a bad block, so that data cannot be written in the PairBlock, which will affect the performance of SPINand

Abstract

The invention discloses a PairBlock erasure error processing method and device. The method includes: erasing data in first block pair PairBlock 1; if errors in erasure of data in the PairBlock 1 is made, acquiring second block pair PairBlock 2 formed by two blank blocks; writing data in the PairBlock 2. When PairBlock erasure errors are made, the new PairBlock is acquired for data writing, and accordingly the problem of failure of the original PairBlock in normal reading and writing or bad blocks is avoided, and SPI Nand stability is improved.

Description

Technical field[0001]The embodiment of the present invention relates to the field of storage technology, and in particular to a method and device for processing a PairBlock erase error.Background technique[0002]Serial Peripheral Interface (SPI) Nand is a type of Flash memory, which belongs to non-volatile memory device (Non-volatile Memory Device). It has the advantages of large capacity and fast rewriting speed, and is suitable for large amounts of data. storage.[0003]There are a variety of data stored in the SPI Nand, and these data are usually stored in a pair of blocks (PairBlock), where each pair of PairBlock includes two blocks, and each block includes several data pages (Page). However, due to the limited number of pages included in each block, when the PairBlock is full or the complete step size is not written, you can switch to another pair of PairBlock first before continuing to write data, and erase the data stored in the PairBlock. If an erase error occurs, the PairBlock...
