发明名称 Flash-based memory system with variable length page stripes including data protection information
摘要 Methods and apparatuses for enhanced protection of data stored in a FLASH memory system involve a controller capable of adapting to the failure of one or more FLASH memory devices in the memory system. The controller stores data in the form of page stripes, each page stripe composed of data pages, and each data page stored in a different FLASH memory device. The controller also detects failure of a FLASH memory device in which a data page of a particular page stripe is stored, reconstructs the data page, and stores the reconstructed data page in a new page stripe, where the number of data pages in the new page stripe is less than the number of data pages in the particular page stripe, and where no page of the new page stripe is stored in a memory location within the failed FLASH memory device.
