one 8-bit encoded symbol for data included within each of a plurality of memory dies of a memory module, thus defining one group of 8-bit encoded symbols.
3. The computer implemented method of claim 2 wherein generating Reed-Solomon parities for each group of encoded symbols includes:
generating the Reed-Solomon parities for the one group of 8-bit encoded symbols.
4. The computer implemented method of claim 1 wherein:
the one or more encoded symbols includes one or more Single Error Correction/Double Error Detection (SECDED) encoded symbols.
5. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
defining one or more encoded symbols for data included within each of a plurality of memory dies of a memory module to define one or more groups of encoded symbols, wherein the one or more encoded symbols for data included within each of the plurality of memory dies of the memory module includes two 4-bit encoded symbols for data included within each of the plurality of memory dies of the memory module;
generating Reed-Solomon parities for each group of encoded symbols, wherein generating the Reed Solomon parities for each group includes generating two distinct Reed-Solomon parities with one Reed-Solomon parity for each of the two groups of 4-bit encoded symbols with one 4-bit symbol available for storing 4-bits of metadata; and
recovering one or more portions of the data included within each of the plurality of memory dies of the memory module in the event of data corruption or die failure using one or more of the encoded symbols and the Reed-Solomon parities.
6. The computer program product of claim 5 wherein the one or more encoded symbols for data included within each of a plurality of memory dies of a memory module includes:
one 8-bit encoded symbol for data included within each of a plurality of memory dies of a memory module, thus defining one group of 8-bit encoded symbols.
7. The computer program product of claim 6 wherein generating Reed-Solomon parities for each group of encoded symbols includes:
generating the Reed-Solomon parities for the one group of 8-bit encoded symbols.
8. The computer program product of claim 5 wherein:
the one or more encoded symbols includes one or more Single Error Correction/Double Error Detection (SECDED) encoded symbols.
9. A computing system including a processor and memory configured to perform operations comprising:
defining one or more encoded symbols for data included within each of a plurality of memory dies of a memory module to define one or more groups of encoded symbols, wherein the one or more encoded symbols for data included within each of the plurality of memory dies of the memory module includes two 4-bit encoded symbols for data included within each of the plurality of memory dies of the memory module;
generating Reed-Solomon parities for each group of encoded symbols, wherein generating the Reed Solomon parities for each group includes generating two distinct Reed-Solomon parities with one Reed-Solomon parity for each of the two groups of 4-bit encoded symbols with one 4-bit symbol available for storing 4-bits of metadata; and
recovering one or more portions of the data included within each of the plurality of memory dies of the memory module in the event of data corruption or die failure using one or more of the encoded symbols and the Reed-Solomon parities.
10. The computing system of claim 9 wherein the one or more encoded symbols for data included within each of a plurality of memory dies of a memory module includes:
one 8-bit encoded symbol for data included within each of a plurality of memory dies of a memory module, thus defining one group of 8-bit encoded symbols.
11. The computing system of claim 10 wherein generating Reed-Solomon parities for each group of encoded symbols includes:
generating the Reed-Solomon parities for the one group of 8-bit encoded symbols.
