With technology scaling, on-chip power dissipation and off-chip memory bandwidth have become significant performance bottlenecks in virtually all computer systems, from mobile devices to supercomputers. An effective way of improving performance in the face of bandwidth and power limitations is to rely on associative memory systems. Recent work on a(More)
Developing ontologies to account for the complexity of biological systems requires the time intensive collaboration of many participants with expertise in various fields. While each participant may contribute to construct a list of terms for ontology development, no objective methods have been developed to evaluate how relevant each of these terms is to the(More)
OBJECTIVE To examine the effect of early initiation of caffeine therapy on neonatal outcomes and characterize the use of caffeine therapy in very low birth weight (VLBW) infants. STUDY DESIGN We analyzed a cohort of 62 056 VLBW infants discharged between 1997 and 2010 who received caffeine therapy. We compared outcomes in infants receiving early caffeine(More)
STUDY DESIGN A comprehensive systematic review of the literature. OBJECTIVES To assess the modern literature on the use of polyethylene mesh-contained morcelized allograft (PMCMA) bone for spinal fusion and vertebral compression fracture management. SUMMARY OF BACKGROUND DATA There are presently no systematic reviews of PMCMA. METHODS A systematic(More)
Novel spin torque transfer magnetic tunnel junction (STT-MTJ) based memory cell topologies are introduced to improve both the sense margin and the current ratio observed by the sense circuitry. These circuits utilize an additional transistor per cell in either a diode connected or gate connected manner and maintain leakage current immunity within the data(More)
—A field driven approach to STT-MRAM switching is proposed as a method for reducing the switching latency of an MTJ in high performance caches. An MRAM array model is presented to characterize the switching energy and maximum achievable reduction in energy using the field driven approach. The switching latency per bit is reduced by more than a factor of(More)
Over the past years, new memory technologies such as RRAM, STT-MRAM, and PCM have emerged. These technologies employ devices located within the metal layers of the integrated circuit, which are relatively fast, dense, and power efficient and can be considered as 'memristors.' In this paper, we present these emerging memory technologies as enablers to the(More)
