发明名称 Method for correction of errors in a binary word stored in multi-level memory cells, with minimum number of correction bits
摘要 <p>The method for correction comprises the step of executing the following steps, for each set of bits in the binary word stored in a single memory cell: a) assigning, to each single error, an error code which is not assigned to other errors; b) for each sub-set of multiple errors, carrying out the following steps: b1) assigning to the sub-set of multiple errors an error code, which is dependent on the error codes assigned to each of the individual errors in the sub-set itself; b2) checking whether the error code assigned to the said sub-set has already been assigned to other errors; b3) if the error code assigned to the said sub-set has already been assigned to other errors, carrying out the following steps: b31) rejecting the error code assigned to the said sub-set, and at least one of the error codes assigned to one of the single errors in the sub-set itself; b32) assigning to the single error assigned to the error code rejected, a new error code, which is not assigned to other errors; and b33) repeating the steps from b1) to b3), until the error code assigned to the sub-set of multiple errors is not assigned to other errors. &lt;IMAGE&gt;</p>
