ABSTRACT: SRAM area is expected to exceed 90% of overall chip area because of the demand for higher performance, lower power, and higher integration. To increase memory density, memory bitcells are scaled to reduce their area by 50% each technology node. High density SRAM bitcells use the smallest devices in a technology, making SRAM more vulnerable for variations. This variation effect the sta...

In this paper, we compare the availability characteristics between three different series system configurations with mixed (cold and warm) standby components and k-stage Erlang repair times. Three configurations are studied under the assumption that the time-to-failure for each of the operative and warm standby components are assumed to be exponentially distributed with parameters λ andα , resp...

‎In this paper‎, ‎a coherent system consisting of non-identical dependent active components and‎ ‎equipped with non-identical dependent standby components is considered‎. ‎The main object of this study is the random quantity‎ ‎which account the number of surviving standby components when the system‎ ‎is failed‎. ‎We represent the distribution function of the corresponding random variable in ter...

BACKGROUND Postvention services aim to ameliorate distress and reduce future incidences of suicide. The StandBy Response Service is one such service operating in Australia for those bereaved through suicide. Few previous studies have reported estimates or evaluations of the economic impact and outcomes associated with the implementation of bereavement/grief interventions. AIMS To estimate the...

In this paper, we propose a five-transistor (5T) static random access memory (SRAM) that can be read and written reliably with the assistance of read/write circuits. The read/write circuits include a voltage control circuit, a pre-charging circuit and a standby start-up circuit. The voltage control circuit is connected to the sources corresponding to driver transistors of each row memory cells....

Some theoretical evaluation methods of mean time to failure (MTTF) in 2-component standby redundant system with priority have been suggested under the prerequisite that the probability distributions of failure and repair times in each component are respectively specified by the explicit functions. However, this prerequisite might be considerably strict in practical scenes. If we cannot identify...

New, small-scale electric generation technologies permit utility customers to generate some of their own electric power and to utilize waste heat for space heating and other applications at the building site. This combined heat and power (CHP) characteristic can provide significant energy-cost savings. However, most current US utility regulations leave CHP standby rate specification largely to ...

We present a new approach for the estimation and optimization of standby power dissipation in large MOS digital circuits. We first introduce a new approach for accurate and efficient calculation of the average standby or leakage current in large digital circuits by introducing the concepts of “dominant leakage states” and the use of state probabilities. Combined with graph reduction techniques ...
