Low-power-consumption power supply

Abstract

The invention relates to a low-power-consumption power supply, which comprises a high-layer power supply network, a bottom-layer power supply network, a transition-layer power supply network, a first hole, a second hole and a switch unit, the high-layer power supply network is specifically one layer or two layers of power supply networks used for being connected with a power supply at the top layer; the bottom-layer power supply network is specifically one layer or two layers of power supply networks used for connecting a standard unit and a hard macro in the chip module; the transition-layer power supply network is specifically a power supply network of each layer between the high-layer power supply network and the bottom-layer power supply network; the bottom-layer power supply network is connected with the transition layer power supply network; the switch unit is arranged below the bottom layer power supply network, and is horizontally arranged with the unit and the hard macro; the first hole is connected with the high-layer power network and the switch unit, and the second hole is connected with the switch unit and the transition-layer power network; the standard unit and the hard macro are connected to the transition layer power supply network through the bottom layer power supply network, and are connected or disconnected with a power supply through the switch unit.

Description

technical field [0001] The invention relates to the technical field of microelectronic devices, in particular to a low power consumption power supply. Background technique [0002] In the field of low-power design, the most effective way to reduce power consumption is to turn off the power supply. The reason is that no matter how low the voltage, how small the current, how slow the speed or how small the leakage is, it is not as thorough as turning off the power supply completely. [0003] However, for a working chip, it is obviously unrealistic to turn off the power of the whole chip. Then if the non-working modules in the chip can be turned off, while the working modules continue to work, real low power consumption can be achieved. [0004] In existing chips, the power supply network is realized through layers of metal, the top metal is always in a energized state, and the bottom metal is connected to the top metal through layers of holes for power transmission.
