    摘要： Non-volatile storage devices and techniques for operating non-volatile storage are described herein. One embodiment includes accessing “n” pages of data to be programmed into a group of non-volatile storage elements. The “n” pages are mapped to a data state for each of the non-volatile storage elements based on a coding scheme that evenly distributes read errors across the “n” pages of data. Each of the non-volatile storage elements in the group are programmed to a threshold voltage range based on the data states to which the plurality of pages have been mapped. The programming may include programming the “n” pages simultaneously. In one embodiment, mapping the plurality of pages is based on a coding scheme that distributes a significant failure mode (for example, program disturb errors) to a first of the pages and a significant failure mode (for example, data retention errors) to a second of the pages.

    摘要： Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. Input data is written and staged in the first portion before being copied to the second portion. An error management provides checking the quality of the copied data for excessive error bits. The copying and checking are repeated on a different location in the second portion until either a predetermined quality is satisfied or the number or repeats exceeds a predetermined limit. The error management is not started when a memory is new with little or no errors, but started after the memory has aged to a predetermined amount as determined by the number of erase/program cycling its has experienced.

    摘要： Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. For acceptable quality assurance, conventional error correction codes (“ECC”) have to correct a maximum number of error bits up to the far tail end of a statistical population. The present memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. If excessive error bits (at the far tail-end) occur after writing a group of data to the second portion, the data is adaptively rewritten to the first portion which will produce less error bits. Preferably, the data is initially written to a cache also in the first portion to provide source data for any rewrites. Thus, a more efficient ECC not requiring to correcting for the far tail end can be used.

    摘要： A method for updating routing table information after a node fails in a P2P network is disclosed herein. The method includes: the range of the nodes whose route is directed to the failed node is determined according to the distance between the failed node and the neighboring node of the failed node; the failure information of the failed node is sent to the LDN of the failed node within the node range; and the LDN updates the routing table according to the failure information. A network device and a P2P communication network are also disclosed herein. The embodiments of the present invention enhance the capability of the whole P2P network in perceiving node churn and improve the route search efficiency and system stability of the whole P2P network.
