摘要： A memory controller controls the operation of a non-volatile memory device. The memory device has a data storage section and an erased storage section. The data storage section has a first plurality of blocks and the erased storage section has a second plurality of blocks. Each of the first and second plurality of blocks has a plurality of non-volatile memory bits that are erased together. Further, each block has an associated counter for storing the number of times the block has been erased. The memory controller has program instructions which are to scan the counters associated with the blocks of the first plurality of blocks based upon the count contained in each of the counters associated therewith to select a third block, and to scan the counters associated with the blocks of the second plurality of blocks based upon the count contained in each of the counters associated therewith to select a fourth block. The program instructions are further configured to transfer data from the third block to the fourth block, and associating said fourth block with said first plurality of blocks. Finally the program instructions are configured to erase said third block and incrementing the counter associated with said third block, and associating said third block with said second plurality of blocks. The present invention is also a method of operating a non-volatile memory device in accordance with the above described steps.

摘要： A memory system, an interface system for accessing a physical sector on an electrically erasable media based upon a logical block number, and a method for mapping a logical block number to a physical sector on an electrically erasable media are disclosed. The erasable media has an erase block size larger than a write block size. The interface system interfaces a host processor to an electrically-erasable memory, such as a flash media. The host processor requests access to the memory based on a logical block number. The interface system uses a first portion of the logical block number to determine from a master index table a physical sector number of a table of physical sector numbers corresponding to the logical block number. The interface system uses a second portion of the logical block number to determine from the table of physical sector numbers the physical sector number on the media corresponding to the logical block number. The host processor is provided access to the physical sector having the physical sector number corresponding to the logical block number. A logical block number may be remapped to a physical sector that has been completely erased by updating the table of physical sector numbers corresponding to the logical block number. A plurality of physical sectors, which are marked as discarded are erased simultaneously.

摘要： A circuit interfaces a host processor to an electrically-erasable memory in a memory space, such as a flash media. The memory space defines a plurality of segments, and each of the segments includes a plurality of sectors. A media interface circuit regulates access by the host processor to the electrically-erasable memory in the memory space. Sector valid indication reading circuitry reads at least one sector valid indication from a segment of the media. Sector valid determination circuitry determines a non-defective sector from the at least one sector valid indication read. Sector level segment defect map indication reading circuitry reads a sector-level segment defect map from the sector determined to be non-defective. Sector defect determination circuitry determines, from the sector-level segment defect map read, sectors within the segment that are valid. Access regulation circuitry regulates access to the memory space at least in part on the determinations by the sector defect determination circuitry.

摘要： In a non-volatile memory array where the memory cells in a sector are programmed together and a plurality of sectors form a segment which are erased together, through the use of a free list linking entries in a register with each entry in a register corresponding to a free segment, a free list table is created which readily simplifies searches for segments that are available for erasure. In addition, through the creation of a segment number table and a count index, determination of particular valid sectors in particular segments can be readily identified.

摘要： A host device connected to memory devices, with each memory device having NAND memory chips and an associated controller. Each NAND memory chip can store a page of data in a single write operation, and can read a page of data from NAND memory in a single read operation, with the page being the smallest unit of storage and having a plurality of bits. The controller of each memory chip partitions each page of the associated NAND memory chip into first, second and third locations. The first location is for storage of host data. The second location is for storage of controller meta data. The third location is for storage of meta data of the host device associated with the host data. The host data, meta data of the controller, and meta data of the host device are written into or read from a page in a single operation.
