Instead of the intensive read and write operations as required in RAM based designs, the new memory is based on an array of registers connected with trace-back signals that decode the output bits on the fly. The structure is used together with appropriate clock and power-aware control signals. Based on a 0.35 /spl mu/m CMOS implementation the trace-back back memory consumes energy of 182 pJ.Ubiquitous computingCongressesUbiquitous computing004Institute of Electrical and Electronics Engineers,PQKBPROCEEDING99101456185033212006 1st International Symposium on Wireless Pervasive Computing2521896UNINA
