SRAM cells are used in many applications such as micro and multi core processor. SRAM cell improves both read stability and write ability at low supply voltage. The objective is to reduce the power dissipation of a novel low power 12T SRAM cell. This method removes half-select issue in 6T and 9T SRAM cell. This work proposes new functional low-power designs of SRAM cells with 6T, 9T and 12 transistors which operate at only 0.4V power supply in sub-threshold operation at 45 nm technology. The leakage power consumption of the proposed SRAM cell is thereby reduced compared to that of the conventional six-transistor (6T) SRAM cell. 12T cell obtains low static power dissipation.

Due to the expansion of cities and increase in population, the need for construction of high rise buildings becomes more essential in the society. As earthquakes are of the greatest damaging natural hazards to the buildings, the design and construction of structures which are capable of resisting the adverse effects of earthquakes become necessary. Concrete Filled Steel Tubes (CFSTs) are the steel tubular sections in-filled with concrete and with a composite action. CFSTs are becoming a popular solution for structures located in seismic areas, due to their high strength, excellent ductility and large energy absorption capacity. This study was mainly concentrated to find out the effect of dimensional parameters on the seismic performance of CFSTs. Width - thickness ratio (D/t) and slenderness ratio (L/D) were taken as two parameters and the study was carried out using circular CFST buildings. It was observed that, there will be a particular limit for D/t and L/D ratio upto which the thickness and diameter of the CFSTs can be decreased. At that point the building will show a better seismic performance.
