SEMICONDUCTOR DEVICE HAVING HIERARCHICAL POWER SUPPLY LINE STRUCTURE IMPROVED IN OPERATING SPEED |
摘要 |
Provided is a power supply-to-power supply capacitance cell including a first capacitor connected between a sub power supply line and a sub ground line, a second capacitor connected between a main power supply line and the sub ground line, and a third capacitor connected between the sub power supply line and a main ground line. Thus, a voltage drop of the sub power supply line can be reduced in current consumption of an internal circuit, so that an operation of the internal circuit is stabilized and the operating speed thereof is improved.
