A one-transistor type DRAM includes a floating body storage element connected between a bit line and a source line and controlled by a word line. Each client monitors its own bandwidth, informs a succeeding client in the chain of that bandwidth, compares its own bandwidth with the bandwidth of a preceding client in the chain and, in response to a difference between the compared bandwidths, reorders its position among the clients in the chain. As the design rules are examined, the probability of each component working is calculated. A transistor that detects accumulated charges in the first conductive well and has a threshold modulation function is formed in the second conductive well. The mood patch changes color to indicate the emotional state of an individual. Other embodiments are disclosed.
