Random number generators are an essential part of cryptographic systems. For the highest level of security, true random number generators (TRNG) are needed instead of pseudorandom number generators. In this paper, the stochastic behavior of the spin transfer torque magnetic tunnel junction (STT-MTJ) is utilized to produce a TRNG design. A parallel structure with multiple MTJs is proposed that minimizes...
Current-induced domain wall motion (CIDWM) is regarded as a promising way towards achieving emerging high-density, high-speed and low-power non-volatile devices. Racetrack memory is an attractive concept based on this phenomenon, which can store and transfer a series of data along a magnetic nanowire. Although the first prototype has been successfully fabricated, its advancement is relatively arduous...
Microelectronics has been following Moore's law for almost 40 years. However this trend tends to run out of steam in recent technology nodes. The continuous improvements in the size of the transistors and in the operating frequencies result in serious power consumption, heat dissipation and reliability issues. Spintronics (Nobel Prize of Physics, 2007 awarded to Prof. Fert from Univ. Paris-Sud and...
Conventional CMOS integrated circuits suffer from serve power and scalability challenges as technology node scales into ultra-deep-micron technology nodes. Alternative approaches beyond charge-only based circuits. In particular, spin-based devices or integrated circuits show promising merits to overcome these issues by adding the spin freedom of electrons to the electronic circuits. Spintronics has...
Spin Transfer Torque Magnetic Random Access Memory (STT-MRAM) provides a promising pathway forthe next generation of non-volatile memory and logic chips. The perpendicular magnetic anisotropy (PMA) in CoFeB/MgO/CoFeB magnetic tunnel junction (MTJ) nanopillar provides high thermal stability and low critical current. However, the STT switching mechanism of MTJ has been revealed intrinsically stochastic,...
Reconfigurable computing provides a number of advantages such as low R&D cost and design flexibility compared with application specific logic circuits; however its low power efficiency and logic density limit greatly its wide application. One of the major reasons of this shortcoming is the SRAM based configuration memory, which occupies large die area and consumes high static power. The later...
