Abstract
A method of operating a memory controller to control a memory device includes reading a read vector from the memory device and correcting one or more errors in the read vector, where a power consumed at the correcting is varied according to the number of errors in the read vector.
Claims1
A method of operating a memory controller to control a memory device, the method comprising:
- reading a read vector from the memory device, wherein the read vector comprises a data portion and a parity portion;
- estimating a number of errors from the read vector;
- performing an error search on only the data portion when the estimated number of errors is below a threshold value to determine actual errors in the read vector;
- performing the error search on both the data portion and the parity portion when the estimated number of errors is not below the threshold value to determine actual errors in the read vector;
- and
- correcting the determined actual errors in the read vector.
