Abstract
Embodiments of the present disclosure provide an a circuit including: first logic to compare output data from the shift register with output data from error correcting code circuitry (ECC), to output an error signal in response to a data bit output from the shift register being different from a data bit output from the ECC; second logic for receiving the error signal from the first logic gate, and a correctability signal from the ECC, to output an overwrite signal in response to receiving the error signal and the correctability signal; and a selector receiving the overwrite signal and the data bit of the output data from the ECC, and coupled between a data source and an input line to the shift register. The selector causes the shift register to receive the ECC output in response to receiving the overwrite signal.
