Abstract
A method of extending the life of a segmented memory device, consistent with certain embodiments involves providing a segmented memory device having a plurality of user defined segments with each segment having a starting and an ending address, and wherein the size and number of the segments is user defined; determining that a threshold number of write operations has been reached by reference to a write counter; copying data from a specified one of the segments to a temporary storage location; shifting the starting and ending address of each segment by a specified address increment; moving data stored in each segment except the specified segment by the specified address increment such that all data in the memory device has been shifted by the specified increment except for the data in the specified one of the segments, wherein data at a last segment is fragmented to wrap from an end of the memory device's addressable locations to a beginning of the memory device's addressable locations; copying the data from the specified one of the segments from the temporary storage location to a location shifted by the shift increment; and redefining the segments so that the user definitions rem…
