SiC fiber-reinforced Ti-21Al-29Nb matrix composites with either C and C/Mo duplex coatings were prepared by the foil-fiber-foil (FFF) method, in order to comparatively study the effects of C/Mo duplex coatings on the interface and mechanical properties of the composites. The longitudinal tensile strength of the as-prepared composites was measured at room temperature. In order to study the interfacial...
STT-RAM (Spin-Transfer Torque Random Access Memory) is a second-generation magnetic random access memory (MRAM) technology that is fast, non-volatile, durable, and scalable to future technology nodes [1-2]. In this paper, we present the latest advances in in-plane and perpendicular STT-RAM development and outline STT-RAM's future prospects, applications and roadmap.
The thermal stability of STT-RAM is measured by multiple techniques and compared with theory. The read disturb rate is found to be determined by the standby thermal stability, but the error rate at target read currents is higher than expected. The implication for the design of 1 Gb STT-RAM is that 10 year room temperature data retention as well as 1000 FIT read disturb error rate requires thermal...
In this paper, we present a detailed analysis of our latest statistical MTJ switching data and STT-RAM chip results. We analyze STT-RAM thermal stability and, for the first time, compare the thermal stability parameter obtained from pulse-width dependence measurements with that obtained from read disturb measurements. We also analyze the scalability of STT-RAM, and compare the properties of STT-RAM...
This paper addresses the testing and implementation of a fast process for sequential contingency simulation in order to identify potential cascading modes due to thermal overloads. It also presents computation of the vulnerability index of cascading, based on the estimated likelihood and consequences of cascading outages. The approach described in this paper offers a unique capability to automatically...
