Abstract:
An apparatus includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller includes an interface configured to send control information to a host device. The control information is associated with first parity information. The controller further includes a circuit configured to determine second parity information associated with the control information. The controller is configured to terminate and optionally rollback an operation associated with the control information in response to the first parity information differing from the second parity information. The terminated optionally rolled-back operation associated with the control information may be a non-blocking control sync operation.
