Abstract
A storage system includes: a control processor, configured to: read user data, generate a bit flip array from the user data including limiting a threshold offset range, and select an optimal read threshold set from the bit flip array; and a non-volatile memory array, coupled to the control processor, configured to store the user data; and wherein the control processor is further configured read a sector N with the optimal read threshold set for enhancing performance of the non-volatile memory array.

A storage system comprising:
- a control processor, configured to:
- read user data,
- generate a bit flip array from the user data includes limiting a threshold offset range without an error recovery (ER) circuitry correcting the data, and
- select an optimal read threshold set from the bit flip array;
- and
- a non-volatile memory array, coupled to the control processor, configured to store the user data;
- and
- wherein the control processor is further configured read a sector N with the optimal read threshold set for enhancing performance of the non-volatile memory array.
A method of operation of a storage system comprising:
- reading user data from a non-volatile memory array;
- generating a bit flip array from the user data by limiting a threshold offset range without an error recovery (ER) circuitry correcting the data;
- selecting an optimal read threshold set from the bit flip array;
- and
- reading a sector N with the optimal read threshold set for enhancing performance of the non-volatile memory array.
A non-transitory computer readable medium including instructions for execution, the medium comprising:
- reading user data from a non-volatile memory array;
