Abstract
To control a read sequence of a nonvolatile memory device, a plurality of read sequences are set and the read sequences respectively correspond to operating conditions different from each other. The read sequences are performed selectively based on sequence selection rates respectively corresponding to the read sequences. Read latencies of the respective read sequences are monitored and the sequence selection rates are adjusted based on monitoring results of the read latencies.
Claims20
A method of controlling execution of a read sequence in a nonvolatile memory device, the method comprising:
- setting read sequences, each read sequence of the read sequences respectively corresponding to a different set of operating conditions;
- performing the read sequences based on respective sequence selection rates corresponding to the read sequences;
- monitoring read latencies for each one of the read sequences;
- and
- adjusting at least one of the sequence selection rates based on the monitored read latencies.
