Problems solved by technology

However, the storage space obtained by storing in SLC mode is small, and the storage space obtained by storing in MLC mode or TLC mode is large. For example, the storage space of a Nand chip in SLC mode is 5G, and the Nand chip is changed to MLC. The storage space is 10G in mode
[0004] In the prior art, the storage mode of the Nand chip can be switched automatically. The conversion method is to automatically trigger the chip to switch the storage mode by storing the amount of data. Therefore, the operation flexibility of this method is poor, and it cannot satisfy users well. the actual needs of

Abstract

The invention relates to data storage, belongs to the field of electronic technologies, and discloses a data storage method and a data storage device. The data storage method includes receiving storage mode setting instructions of target storage regions; setting storage modes of the target storage regions as target storage modes in Nand chips; carrying out data storage operation in the target storage regions by the aid of the target storage modes. The target storage modes are carried in the storage mode setting instructions and include single-layer cell (SLC) modes, multiple-layer cell (MLC) modes or three-layer cell (TLC) modes. The data storage method and the data storage device have the advantages that the storage modes of the target storage regions can be voluntarily changed by the aid of the storage mode setting instructions as needed; the storage mode setting instructions can be operated, the storage mode setting or changing operation can be effectively controlled, accordingly, the flexibility of storage mode setting operation can be improved, and actual requirements of users can be effectively met.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a data storage method and device. Background technique [0002] Nowadays, the storage capacity of Nand chips (a kind of computer flash memory chips) is getting larger and larger, and users generally do not use all of their storage space in the initial stage of using Nand chips. Idle and waste. [0003] In order to solve the above problems, when the usage of the Nand chip does not exceed the reserved capacity, the storage mode of the Nand chip can be set to SLC (Single-Level Multi-Level Cell, single-layer unit) mode; when the usage of the Nand chip exceeds When booking the capacity, the storage mode of the Nand chip can be set to MLC (Multi-Level Cell, multi-level cell) mode or TLC (Triple-Level Cell, triple-level cell) mode. SLC mode is more stable than MLC mode and TLC mode, and the writing speed is faster. However, the storage space obtained by storing in SLC mo...
