In our proposed work, we are making our RAM to behave energy efficient by reducing the overall power usage by implementing it on FPGA. LVCMOS15 and LVCMOS25 have been used to observe the power reduction , which includes clock power ,logic power, signal power, i/o power, leakage power and Total power. Power reduction of about 61.4% is seen at the capacitance of 500pF by testing the RAM on LVCMOS25 and then in LVCMOS15. Also the leakage power is comparatively much lower at-33 degree Celsius with the capacitance load of 1000pF in LVCMOS25. The FPGA is tested on different temperatures including standard room temperature of 25 degree celsius,-33 degree and 48.9degree celsius which is environmentally extreme temperature .The results are obtained by using Xilinx ISE 14.7 simulator with verilog hardware description language.
