    摘要: Tracking cells are used in a memory system to improve the read process. The tracking cells can provide an indication of the quality of the data and can be used as part of a data recovery operation if there is an error. The tracking cells provide a means to adjust the read parameters to optimum levels in order to reflect the current conditions of the memory system. Additionally, some memory systems that use multi-state memory cells will apply rotation data schemes to minimize wear. The rotation scheme can be encoded in the tracking cells based on the states of multiple tracking cells, which is decoded upon reading.

    摘要: Methods and apparatus for transforming data into a format which may be efficiently stored in a non-volatile memory are disclosed. According to one aspect of the present invention, a method for storing information of a first data format in a memory system includes generating statistics associated with the first data format, and transforming the information from the first data format to a second data format using the statistics. Once the information is transformed into the second data format, the information is stored into a memory. Storing the information in the second data format in the memory includes storing an identifier that identifies a transformation used to transform the information to the second data format. In one embodiment, costs associated with storing the information in the second data format are less than or equal to costs associated with storing the information in the first data format.

    摘要: A portion of data stored in a non-volatile memory may be found to be corrupted when it is read. Where parity data is generated from portions of data and the parity data is stored with the portions of data, the corrupted data may be reconstructed from the parity data and uncorrupted portions of data.

    摘要: A process is provided for producing improved, superior and more cost effective glass micro fibers, wherein molten glass in filament form is attenuated into glass micro fibers by gasses of a combusted mixture of air and fuel. The improvement comprises introducing into the mixture a gas stream containing at east 70% by volume of oxygen. This avoids problems in glass micro fiber production where the quality of the fibers varies from time to time, as demonstrated by the quality of paper produced therefrom. An apparatus for producing the fibers is also provided, as well as improved glass micro fibers and improved papers made therefrom.
