Abstract: A flash-memory system is organized into a plurality of blocks and a plurality of pages in each block, each page having 2N data locations and K spare locations. At least one page in the memory has 2M user data sectors and each sector has 2N-M+L locations therein. Because L is at least 1 but less than 2N-M, user data is stored in the spare memory locations. By storing user data in spare locations that were previously off-limits to user data, enterprise-sized sectors can be efficiently stored in flash memories with little wasted memory, thereby making flash-memory systems compatible with existing hard-drive storage systems in enterprise system applications.

Abstract: A flash-memory system is organized into a plurality of blocks and a plurality of pages in each block, each page having 2N data locations and K spare locations. At least one page in the memory has 2M?1 user data sectors and each sector has 2N-M+L locations therein. Error-correction code (ECC) data related to the user data is calculated and stored in at least the 2M user data locations unused by the 2M?1 user data sectors. Because L is at least 1 but less than 2N-M (N>M), at least a portion of one user data sector is stored in the spare memory locations. Additional locations in each page are available to allow for the ECC data to have additional redundancy bits added per sector, thereby making the flash memory system more robust and reliable.
