  • About the Laboratory & Research Area
  • ▶ Introduction of Lab.
    In nano-scale device group in Semiconductor Materials and Devices Laboratory (SMDL), we have made our efforts on design and fabrication of non-volatile memories (NVM), tunneling devices, and neuromorphic system.
    For the realization of high density NVM, various types of 3-dimensional stacked SONOS flash memories and resistive random access memory (RRAM) are proposed and fabricated. And, tunneling field-effect transistors (TFETs) for fast on-off switching device have been carried out. Recently, for the realization of neuromorphic system, some studies about synaptic device are ongoing.
