CONTROLLER AND OPERATING METHOD THEREOF FOR DETERMINING RELIABILITY DATA BASED ON SYNDROME WEIGHT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17960238 titled 'CONTROLLER AND OPERATING METHOD THEREOF FOR DETERMINING RELIABILITY DATA BASED ON SYNDROME WEIGHT
Simplified Explanation
The abstract describes a controller that includes a storage memory, a decoder, and a processing circuit.
- The storage memory stores N-bit read data and N reliability data units.
- The decoder performs a decoding operation on the read data using the reliability data units.
- The processing circuit determines the value of a reliability data unit based on the corresponding bit of the read data, the corresponding bit of another read data, and the difference between the syndrome weights of the two read data.
- The invention aims to improve the reliability of data decoding in a controller.
Original Abstract Submitted
A controller may include i) a storage memory configured to store N-bit read data and N reliability data units, ii) a decoder configured to execute a decoding operation for the read data based on the reliability data units, and iii) a processing circuit configured to determine a value of reliability data unit corresponding to I-th bit of read data based on an I-th bit of first read data, an I-th bit of second read data and a difference between first syndrome weight and second syndrome weight.
