Suppressing the leakage current in memories is critical in low-power design. By reducing the standby supply voltage (VDD) to its limit, which is the data retention voltage (DRV), leakage power can be substantially reduced. This paper models the DRV of a standard low leakage SRAM module as a function of process and design parameters, and analyzes the SRAM cell stability when VDD approaches DRV. ...

As the technolody node shrinks down to 90nm and below, high standby power becomes one of the major critical issues for CMOS highspeed computing circuits (e.g. logic and cache memory) due to the high leakage currents. A number of non-volatile storage technologies, such as FRAM, MRAM, PCRAM and RRAM, are under investigation to bring the non-volatility into the logic circuits and then eliminate co...

In this paper a model for dynamic fault tree (FT) analysis is developed. The model is ussed for the analysis of a cold standby redundant system. It is shown that a typical modern fault tree analysis (FTA), resulting in the Boolean domain in a short pseudopolynomial, i.e., a polynomial in the literals of the FT input variables, can yield grave errors in case of cold standby, even though the sing...

In Indiana v. Edwards (2008) the U.S. Supreme Court held that a higher standard may be required for pro se competence (PSC) than for competence to stand trial (CST), but provided little guidance for the trial court judge. This survey of forensic mental health experts studied potential PSC criteria. Sixty-eight (22.7%) forensic evaluators replied. Three McGarry criteria were reported as requirin...

In this paper, zigbee communication based wireless energy surveillance system is presented. The proposed system consists of multiple energy surveillance devices and an energy surveillance monitor. Each different standby power-off value of electric device is set automatically by using learning function of energy surveillance device. Thus adaptive standby power-off function provides user convenie...

General-purpose, high-availability database systems have lately proliferated to various network element platforms. In telecommunication, databases are expected to meet demanding availability levels while preserving the required throughput. However, so far, the effects of various high-availability configurations on overall database performance have not been analyzed. In this paper, the operation...

The integrated PWM controller features include a proprietary green-mode function that provides off-time modulation to linearly decrease the switching frequency at light-load conditions to minimize standby power consumption. The PWM controller is manufactured using the BiCMOS process to further reduce power consumption. The green and burst modes function with a low operating current (2.5mA in gr...

We present in this paper the method of Generalized Nodal Control for standby leakage power reduction. First, a sparse set of input and internal nodes to control are identified using a novel algorithm based on Reduced Ordered Binary Decision Diagrams (ROBDDs) and Fiduccia-Mattheyses Partitioning. Then, customized control gates with ”forced” transistor stacks are inserted at these select location...
