Master's thesis:
CRRC: Coordinating Retention Errors, Read Disturb Errors and Huffman Coding on TLC NAND Flash Memory


Abstract:
Nowadays, TLC NAND flash memory has become a mainstream storage medium because of its large capacity and low cost. However, TLC NAND flash memory could have reliability problems (such as the retention errors and the read disturb errors), as the cell capacity increases. 

Because the reasons for the retention errors and the read disturb errors are due to 8 different states in a TLC cell, we will propose a method to coordinate the retention errors, the read disturb errors and the Huffman coding on TLC NAND flash memory by removing some unsuitable states when different data accesses are considered

According to the experimental results, the proposed method can utilize the compression of the Huffman coding to improve performance.  In addition, the proposed method can also remove the unsuitable states that are susceptible to retention errors or read disturb errors to enhance the reliability of TLC NAND flash memory.

College Internship - Embedded Software Development

Feng Sheng Digital. Tech  •  六月 2018 - 四月 2019

During the college internship, I participated in the JTL(喜特麗) IoT smart water heater project.

Using ESP32 microprocessor of Espressif, which uses RTOS as the framework of the SDK, so I learned the knowledge related to RTOS (e.g., mutex, semaphore, priority scheduling) by myself.

I also learned about some common communication applications of the Internet of Things, MQTT, NBIOT (SIM7000) by participating in other projects in the company.
