Abstract
A device with error correction is provided. The device includes a plurality of memory cells, and reference read write circuit, a plurality of sense amplifiers, and an error-correction code control block. The reference read write circuit is configured to generate a reference voltage in response to data stored in at least one of the plurality of memory cells. A plurality of sense amplifiers are each coupled to a respective memory cell of the plurality of memory cells. An error-correction code (ECC) control block may output an error signal when the ECC control block detects that it is unable to correct error data in one or more respective memory cells. The reference read write circuit may overwrite data in the at least one of the plurality of memory cells in response to the error signal.
