Abstract
Embodiments herein provide for a controller that is operable to soft read a data bit a plurality of times, to generate a bit set for the data bit from the soft reads, to logically operate on the bit set, and to generate a Hamming weight for the data bit based on the logical operation. The Hamming weight has fewer bits than the bit set and is operable to correct the data bit.
Claims20
A system, comprising:
- a controller operable to soft read a data bit a plurality of times, to generate a bit set for the data bit from the soft reads, to logically operate on the bit set, and to generate a Hamming weight for the data bit based on the logical operation, the Hamming weight having fewer bits than the bit set and being operable to correct the data bit.
A method, comprising:
- soft reading a data bit a plurality of times;
- generating a bit set for the data bit from the soft reads;
- logically operating on the bit set;
- and
- generating a Hamming weight for the data bit based on the logical operation, the Hamming weight having fewer bits than the bit set and being operable to correct the data bit.

A non-transitory computer readable medium comprising instructions that, when executed by a controller of a storage system, direct the controller to:
- soft read a data bit a plurality of times;
- generate a bit set for the data bit from the soft reads;
- logically operate on the bit set;
- and
- generate a Hamming weight for the data bit based on the logical operation, the Hamming weight having fewer bits than the bit set and being operable to correct the data bit.
