This paper analyzes write errors in spin-torque switching due to thermal fluctuations in a system with perpendicular magnetic anisotropy. Prior analytical and numerical methods are summarized; a physics-based general 2-D Fokker-Planck equation (FPE) is solved numerically. Due to its computational efficiency and broad applicability to all switching regimes(More)
Emerging spintronics and nanomagnetic devices have attracted a lot of attention due to their versatility, scalability and energy efficiency. Most spintronics applications require manipulation of nano-magnet in a fast and efficient way. Spin transfer torque (STT) effect[1] is so far the most studied and well demonstrated means to switch a nano-size magnetic.(More)
Dipole-coupled nanomagnetic logic (NML), where nanomagnets (NMs) with bistable magnetization states act as binary switches and information is transferred between them via dipole-coupling and Bennett clocking, is a potential replacement for conventional transistor logic since magnets dissipate less energy than transistors when they switch in a logic circuit.(More)
Due to challenges related to physical and electrical scaling, metal-oxide-semiconductor field-effect transistor (MOSFET)-based memory technology is now suffering from increased power leakage and endurance problems. For instance, static random access memory (SRAM) and dynamic random access memory (DRAM) are both volatile, and cannot maintain data when the(More)
STT-RAMs show the promise to be the universal memory device with applications in embedded devices. There are outstanding challenges that need to be addressed before a wide-scale adoption of this technology happens. The solution to these challenges lie in integration of emerging high performance spintronic materials as well as clever circuit based techniques(More)
