Introduction

Yudi Dou is an inventor associated with Singapore and Tetramem Inc. Her patent work addresses error detection and correction in multi-level cell-based memory devices, where reliable data retrieval is essential.

Latest Patents

Dou is associated with 1 patent: “Enhanced Error Correction Code for Error Detection and Correction in Multi-Level Cell-Based Memory Devices.” The invention describes methods in which an error-correction-code decoder receives encoded data from a memory device and uses Reed–Solomon error-correction coding to calculate an error value and location. It classifies errors as absent, single-symbol, or multiple-symbol errors using a +1/−1 error constraint. When multiple-symbol errors are detected, the method repeats the read from the memory device.

Career Highlights

Dou’s listed patent reflects work on improving the reliability of data stored in multi-level cell-based memory. The approach combines error analysis with a repeat-read response to address cases involving multiple symbol errors.

Collaborations

The patent information names Lei Liu and Jun Sheng Ng as Dou’s coworkers. The invention is associated with Tetramem Inc.

Conclusion

Yudi Dou’s patent focuses on strengthening error detection and correction for multi-level cell-based memory, contributing a method for identifying error types and responding to multiple-symbol errors.
