摘要： Discarded memory devices unfit for an original purpose can be reclaimed for reuse for another purpose. The discarded memory devices are tested and evaluated to determine the level of performance degradation therein. A set of an alternate usage and an information encoding scheme to facilitate a reuse of the tested memory device is identified based on the evaluation of the discarded memory device. A memory chip controller may be configured to facilitate usage of reclaimed memory devices by enabling a plurality of encoding schemes therein. Further, a memory device can be configured to facilitate diagnosis of the functionality, and to facilitate usage as a discarded memory unit. Waste due to discarded memory devices can be thereby reduced.

摘要： Error correction in not-and (NAND) flash memory including a system for retrieving data from memory. The system includes a decoder in communication with a memory. The decoder is for performing a method that includes receiving a codeword stored on a page in the memory, the codeword including data and first-tier check symbols that are generated in response to the data. The method further includes determining that the codeword includes errors that cannot be corrected using the first-tier check symbols, and in response second-tier check symbols are received. The second-tier check symbols are generated in response to receiving the data and to the contents of other pages in the memory that were written prior to the page containing the codeword. The codeword is corrected in response to the second-tier check symbols. The corrected codeword is output.

摘要： Memory cell presetting for improved performance including a method for using a computer system to identify a region in a memory. The region includes a plurality of memory cells characterized by a write performance characteristic that has a first expected value when a write operation changes a current state of the memory cells to a desired state of the memory cells and a second expected value when the write operation changes a specified state of the memory cells to the desired state of the memory cells. The second expected value is closer than the first expected value to a desired value of the write performance characteristic. The plurality of memory cells in the region are set to the specified state, and the data is written into the plurality of memory cells responsive to the setting.
