Research goal
- Design of non-volatile logic circuit through understanding of characteristics of next-generation non-volatile devices such as spin transfer torque magnetic tunnel junction (STT-MTJ) and ferroelectric FET (FeFET)
- Exploration of applications of non-volatile logic and system-level verification
Description
- As the technology node scales down, the energy and time required to transfer data to memory through global interconnect has been dominant. Designing non-volatile logic which integrates nonvolatile memory in logic circuit can resolve the energy/time overhead derived from data transfer. Moreover, the non-volatile logic can significantly reduce standby power required for data storage.
Research goal
- Design of Physically Unclonable Function (PUF) cell structure with high level of stability to generate cryptographic code
- Development of post processing techniques applicable to PUF for reduced bit error rate
Description
- With the progress of IoT, demand for cryptograph has grown due to higher level of security. Physically Unclonable Function (PUF) satisfies the role of both generator and storage of cryptograph. A PUF should generate identical security keys with the reference keys for authentication which is one of important PUF applications. Designing PUF with reduced bit error rate (BER) at environmental variation leads to correct security application.
