Title: Yi-Fan Chang: Semiconductor Data-Transfer Invention

Introduction

Yi-Fan Chang is an inventor based in Hsinchu, Taiwan. His work includes an invention for managing data transfers in semiconductor devices, and he is associated with Macronix International.

Latest Patents

Chang is credited with 1 patent. The patent, “Managing Data Transfers in Semiconductor Devices by Separating Circuits for Lower-Speed-Type Data and Higher-Speed-Type Data,” describes systems, methods, circuits, and devices that route higher- and lower-speed data through separate logic circuits before outputting it through a driving circuit.

The method selects an interface for each data type. Higher-speed data travels along a first data path, while lower-speed data travels along a second path. Both interfaces receive data at the same clock frequency, but the higher-speed data is transferred faster than the lower-speed data.

Career Highlights

Chang’s patent work addresses data-transfer management in semiconductor devices. The invention’s separate paths and logic circuits are designed to handle data operating at different speeds while using a shared driving circuit.

Collaborations

The patent lists Su-Chueh Lo and Jeng-Kuan Lin as collaborators.

Conclusion

Yi-Fan Chang’s documented invention focuses on separating data paths for different transfer speeds in semiconductor devices, reflecting his contribution to semiconductor technology at Macronix International.
