—Cryptography circuits for smart cards and portable electronic devices provide user authentication and secure data communication. These circuits should, in general, occupy small chip area, consume low power, handle several cryptography algorithms , and provide acceptable performance. This paper presents, for the first time, a hardware implementation of(More)
—This paper presents two circuit implementations for the differential capacitance read scheme (DCRS) in ferroelectric random-access memories (FeRAM). Compared to the conventional read scheme, DCRS achieves a faster read access by activating the sense amplifiers immediately after a wordline is activated. By relying on the capacitance difference instead of(More)
