MEMORY DEVICE AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17718422 titled 'MEMORY DEVICE AND OPERATING METHOD THEREOF
Simplified Explanation
The abstract describes an operating method for a memory device that includes storing position information about a codeword with an erasure and erasure information in a memory region. When a read instruction is received from a host, the position information of the erasure is transmitted to an error correction code (ECC) decoder, which corrects errors in the codeword using the position information of the erasure.
- The method involves storing position information about a codeword with an erasure in a memory region.
- The position information of the codeword is loaded to a row decoder and a column decoder.
- When a read instruction is received, the method determines if the read address matches the position information of the codeword with the erasure.
- If there is a match, the position information of the erasure is transmitted to an ECC decoder.
- The ECC decoder then corrects errors in the codeword received from the memory cell array using the position information of the erasure.
Potential Applications
- This operating method can be applied in various memory devices, such as solid-state drives (SSDs) and flash memory.
- It can be used in systems that require reliable and efficient error correction in memory operations.
Problems Solved
- The method solves the problem of errors in codewords with erasures in memory devices.
- It provides a mechanism to identify and correct errors using position information of the erasure.
Benefits
- The method improves the reliability and accuracy of memory operations by correcting errors in codewords with erasures.
- It enhances the overall performance of memory devices by efficiently handling erasure information.
- The method simplifies the error correction process by utilizing position information of erasures.
Original Abstract Submitted
An operating method of a memory device includes storing position information regarding a codeword including an erasure and erasure information including position information regarding the erasure in a memory region, loading the position information regarding the codeword to a row decoder and a column decoder, determining whether a read address corresponding to a read instruction is identical to the position information regarding the codeword including the erasure, in response to the read instruction from a host, transmitting the position information of the erasure to an error correction code (ECC) decoder, when the read address is identical to the position information regarding the codeword including the erasure, and correcting, by the ECC decoder, an error in a codeword received from a memory cell array using the position information regarding the erasure.
