Leakage Current: Moore''s Law Meets Static Power
Off-state leakage is static power, current that leaks through transistors even when they are turned off. The other source of power dissipation in today''s microprocessors, dynamic power, arises from the repeated capacitance charge and discharge on the output of the hundreds of millions of gates in today''s chips. Until recently, only dynamic
