    Abstract: 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.

    Abstract: 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.

    Abstract: Methods and apparatus for reducing read access times associated with obtaining stored data from a non-volatile memory system are disclosed. According to one aspect of the present invention, a method for providing data to a bus within a memory system that includes a storage area involves providing a first signal (REM) within the memory system and enabling an output buffer in response to the first signal. The first signal indicates that the data is to be provided to the bus from the storage area, and is of a first level which has a first duration. The output buffer provides the data from the storage area to the bus, and remains substantially enabled while the first signal is of the first level. In one embodiment, the method also includes providing a second signal (OE) as an input to the output buffer to enable the output buffer.
