The subject of this invention relates to method carburizing of steel products, mainly parts of machines, vehicles and every mechanical apparatus, in vacuum furnaces under reduced pressure and elevated temperature. In the method, trenches are formed in a silicon substrate corresponding to a source region and a drain region. In at least one embodiment, by coordinating functions, , and, the controller controls a power converter system that is compatible with a triac-based dimmer. The electronic mail may include information relating to operation of the power system or to operation of the intelligent electronic device. However, on misses, a processor can cause memory allocation only within its associated region or regions. The method includes placing a small positive voltage on the unselected source lines, andor a small negative voltage on the unselected word lines, during the read operation to suppress sub-threshold leakage and thereby improve read performance.
