Implementing Decay Techniques using Quasi-Static Memory Cells

چکیده
This paper proposes the use of four-transistor (4T) cache and branch predictor array cell designs to address increasing worries regarding leakage power dissipation. While 4T designs lose state when infrequently accessed, they have very low leakage, smaller area, and no capacitive loads to switch. This short paper gives an overview of 4T implementation issues and a preliminary evaluation of leakage-energy savings that shows improvements of 60-80%.

Managing Leakage for Transient Data: Decay and Quasi-Static Memory Cells
Much of on-chip storage is devoted to transient, often short-lived, data. Despite this, virtually all on-chip array structures use sixtransistor (6T) static RAM cells that store data indefinitely. In this paper we propose the use of quasi-static four-transistor (4T) RAM cells. Quasi-static 4T cells provide both energy and area savings. These cells have no connection to Vdd thus inherently provi...
متن کاملLow Power March Memory Test Algorithm for Static Random Access Memories (TECHNICAL NOTE)
Memories are most important building blocks in many digital systems. As the Integrated Circuits requirements are growing, the test circuitry must grow as well. There is a need for more efficient test techniques with low power and high speed. Many Memory Built in Self-Test techniques have been proposed to test memories. Compared with combinational and sequential circuits memory testing utilizes ...
متن کاملOn the asymptotic behavior of the quasi-static problem for a linear viscoelastic fluid
In this paper we study the quasi-static problem for a viscoelastic fluid by means of the concept of minimal state. This implies the use of a different free energy defined in a wider space of data. The existence and uniqueness is proved in this new space and the asymptotic decay for the problem with non vanishing supplies is obtained for a large class of memory kernels, including those presentin...
متن کاملLocal viscoelastic properties of live cells investigated using dynamic and quasi-static atomic force microscopy methods.
The measurement of viscoelasticity of cells in physiological environments with high spatio-temporal resolution is a key goal in cell mechanobiology. Traditionally only the elastic properties have been measured from quasi-static force-distance curves using the atomic force microscope (AFM). Recently, dynamic AFM-based methods have been proposed to map the local in vitro viscoelastic properties o...
متن کاملDesign of Leakage Power Reduced Static RAM using LECTOR
The scaling down of technology in CMOS circuits, results in the down scaling of threshold voltage thereby increasing the sub-threshold leakage current. LECTOR is a technique for designing CMOS circuits in order to reduce the leakage current without affecting the dynamic power dissipation, which made LECTOR a better technique in leakage power reduction when compared to all other existing leakage...
