  • Patent number: 10170195
    Abstract: A controller adapts read voltage thresholds of a non-volatile memory. In one embodiment, in response to selection of a block for adaptation of at least one read voltage threshold applicable to a physical page of the block, the controller issues a dummy read operation to the block to ensure the physical page is in a lower bit error rate (BER) state. The controller waits for a calibration read wait period following the dummy configuration read operation and, during the calibration read wait period, monitors for an interfering access to the non-volatile memory that would temporarily place the physical page in a higher BER state. In response to not detecting the interfering access during the calibration read wait period, the controller performs a calibration read operation for the physical page and adapts at least one read voltage threshold for the physical page based on results of the calibration read operation.
