Abstract
Methods and apparatuses for enhanced protection of data stored in a FLASH memory system involve a controller capable of using variable size page stripes in the memory system. The controller is configured to store data such that each page stripe comprises a plurality of data pages, with each data page in the page stripe being stored in a different FLASH memory chip. The controller is also configured to maintain one or more buffers containing information reflecting blocks of memory within the FLASH memory chips that have been erased and are available for information storage, and to dynamically determine the number of data pages to be included in a page stripe based on the information in the one or more buffers such that a first page stripe and a second page strip can have different numbers of data pages.
