Wei-Chih (Richard) Chien

Dr. Wei-Chih (Richard) Chien is a semiconductor research and development professional with nearly two decades of experience in advanced memory technologies and process integration. His expertise covers Phase Change Memory (PCM), Resistive RAM (ReRAM), Cross-Point Memory, and Selector-Only Memory, with a focus on device physics, reliability, and cross-functional design collaboration. 

Dr. Chien previously served as a Principal Researcher at the National Center for the Advancement of Semiconductor Technology (Natcast), where he helped bridge research efforts between academia and industry to support the National Semiconductor Technology Center’s (NSTC) initiatives. Before that, he led collaborative projects between Macronix and IBM at the IBM T.J. Watson Research Center, advancing emerging non-volatile memory solutions for embedded and storage-class applications. Earlier in his career, he contributed to ReRAM and MRAM device development at Macronix International and ITRI Taiwan. 

He has authored over 80 peer-reviewed papers—including 11 presented at IEDM and 14 at VLSI—and holds more than 30 U.S. patents. Dr. Chien has also served on IEDM’s Memory Technology and Nano Device Technology subcommittees and received multiple recognitions for his technical contributions.
