METHODS AND DEVICES FOR AVOIDING LOWER PAGE CORRUPTION IN DATA STORAGE DEVICES |
摘要 |
A data storage device may comprise a plurality of Multi-Level Cell (MLC) non-volatile memory devices comprising a plurality of lower pages and a corresponding plurality of higher-order pages. A controller may be configured to write data to and read data from the plurality of lower pages and the corresponding plurality of higher-order pages. A buffer may be coupled to the controller, which may be configured to accumulate data to be written to the MLC non-volatile memory devices, allocate space in the buffer and write the accumulated data to the allocated space. At least a portion of the accumulated data may be written in a lower page of the MLC non-volatile memory devices and the space in the buffer that stores data written to the lower page may be de-allocated when all higher-order pages corresponding to the lower page have been written in the MLC non-volatile memory devices. |
