We will present high performance/low-cost spin transfer torque magnetic random access memory (STT-MRAM) solution based upon 64Mb chip data and scalable magnetic tunneling junction (MTJ) BEOL integration scheme at 55 nm process node. This is the first fully functional STT-MRAM chip fabricated in a top tier foundry using the standard 300 mm CMOS foundry process. We will characterize pMTJ device population...
The influences of solid surface on the propagation of creepage discharge in liquids were investigated under ac divergent electric field. Synchronized phase-resolved partial discharge (PD) detection, wideband current measurement and streamer channel visualization were employed to study the differences of discharge patterns between in open gap and on solid surface and to explore the mechanisms behind...
Reactive power plays a crucial role in power system operation and voltage management. However reactive power issues have rarely been considered in reliability evaluation of power systems. This paper investigates the effect of reactive power on reliability of the 220 kV Taiyuan Power System in Shanxi Province of China. Reactive power shortage and the associated voltage violations due to the failures...
This paper reports the design, modeling, fabrication and measurement of a CMOS-compatible surface-micromachined test structure for the determination of the thermal conductivity of thin films based on the Seebeck effect. The Seebeck effect-based temperature sensing is more advantageous for thin film materials with a relatively large Seebeck coefficient, such as lightly doped poly-Si and poly-SiGe....
A CMOS circuit is presented which performs all analog interface functions to a standard telephone subscriber line including DC and AC termination, send and receive amplification, anti-side-tone network, line loss compensation, and dialing control. All transmission parameters are software programmable and are loaded into the IC during hook-off or, if necessary, during conversation. It is fabricated...
