Latest Patents

Ng’s patent, “Enhanced Error Correction Code for Error Detection and Correction in Multi-Level Cell-Based Memory Devices,” describes methods for improving the reliability of data stored in multi-level cell memory. The approach uses Reed-Solomon error correction code to calculate an error value and locate an error in data received by an ECC decoder.

The method classifies errors as no error, a single-symbol error, or multiple-symbol errors, using a +1/−1 error constraint. When multiple-symbol errors are identified, the system repeats the read from the memory device. This process is designed to support more effective error detection and correction.

Career Highlights

Ng’s listed patent focuses on memory reliability and hardware-based error correction. His work combines Reed-Solomon coding with error classification and a repeat-read response to address errors in multi-level cell-based storage.
