摘要： Multiple logical pages are jointly encoded into a single code word and are stored in the same physical page of a solid state non-volatile memory (NVM) device having multi-level memory cells. A first logical page of the multiple logical pages is stored in the memory device as first bits of the multi-level memory cells while a second logical page of the multiple logical pages is temporarily cached. After the first logical page is stored as the first bits of the memory cell, the second logical page is stored as second bits of the memory cells.
摘要翻译：多个逻辑页面被联合编码成单个码字，并被存储在具有多层存储器单元的固态非易失性存储器（NVM）设备的相同物理页面中。多个逻辑页面的第一逻辑页面被存储在存储器设备中作为多级存储器单元的第一位，而多个逻辑页面的第二逻辑页面被临时高速缓存。在将第一逻辑页面存储为存储器单元的第一位之后，第二逻辑页面被存储为存储器单元的第二位。

摘要： Methods and systems for accessing encoded data stored in a solid state non-volatile memory device include iteratively demodulating and decoding the data. The memory device includes memory cells arranged to store multiple bits of data per memory cell. The memory cells are capable of storing multiple pages of data. Each bit stored in a memory cell is associated with a page of data that is different from other pages associated with other bits stored in the memory cell. The multiple pages are demodulated responsive to sensed voltage levels of the memory cells, and a demodulated output is provided for each page of the multiple pages. A decoded output for each page of the multiple pages is generated. Decoding the page and demodulating the multiple pages proceeds iteratively, including an exchange of information between the decoder and the demodulator.

摘要： A multi-dimensional recording (MDR) system may include a group based coding circuit (GBCC) which can implement error correcting codes via outer codes. The GBCC can implement outer codes, including interleaving outer codes, in MDR systems where inner codewords include multiple memory groupings. The multiple memory groupings may be across different structural divisions within a data storage medium; or could be across multiple different data storage mediums.
