READ RECOVERY INCLUDING LOW-DENSITY PARITY-CHECK DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17887813 titled 'READ RECOVERY INCLUDING LOW-DENSITY PARITY-CHECK DECODING
Simplified Explanation
The abstract describes a method for generating a sign bit of a low-density parity-check (LDPC) codeword associated with a translation unit (TU) by performing an XOR operation on a RAIN drop corresponding to the TU and a raw read of the TU. The LDPC codeword includes a hard bit and three soft bits that include the sign bit, which can be decoded using the hard bit and the three soft bits. A read recovery operation can be performed on the TU using the decoded LDPC codeword.
- Sign bit of LDPC codeword generated by XOR operation on RAIN drop and raw read of TU
- LDPC codeword includes hard bit and three soft bits with sign bit
- Decoding of LDPC codeword using hard bit and three soft bits
- Read recovery operation on TU using decoded LDPC codeword
Potential Applications
- Error correction in data storage systems
- Communication systems requiring reliable transmission of data
Problems Solved
- Error detection and correction in data transmission
- Improving reliability of data storage systems
Benefits
- Enhanced data integrity
- Improved error correction capabilities
- Increased reliability in data transmission and storage.
Original Abstract Submitted
A sign bit of a low-density parity-check (LDPC) codeword associated with a translation unit (TU) can be generated by performing an XOR operation on a RAIN drop corresponding to the TU and a raw read of the TU. The LDPC codeword can include a hard bit and three soft bits that include the sign bit. The LDPC codeword can be decoded using the hard bit and the three soft bits. A read recovery operation can be performed on the TU using the decoded LDPC codeword.
