METHODS AND APPARATUS FOR STORING DATA IN A MULTI-LEVEL CELL FLASH MEMORY DEVICE WITH CROSS-PAGE SECTORS, MULTI-PAGE CODING AND PER-PAGE CODING

摘要

Methods and apparatus are provided for storing data in a multi-level cell flash memory device with cross-page sectors, multi-page coding and per-page coding. A single sector can be stored across a plurality of pages in the flash memory device. Per- page control is provided of the number of sectors in each page, as well as the code and/or code rate used for encoding and decoding a given page, and the decoder or decoding algorithm used for decoding a given page. Multi-page and wordline level access schemes are also provided.
