POWER SUPPLY SWITCHING CIRCUIT AND MEMORY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18327062 titled 'POWER SUPPLY SWITCHING CIRCUIT AND MEMORY

Simplified Explanation

The patent application describes a power supply switching circuit that reduces the time required to turn on or off different output subcircuits simultaneously. This improves the efficiency and reliability of the device.

  • The power supply switching circuit generates control signals using input signals and drive signals that are opposite in phase.
  • By utilizing these control signals, the circuit reduces or eliminates the overlap time needed to turn on or off different output subcircuits.
  • This allows for more effective output from the device and improves its reliability.
  • Compared to other methods of eliminating overlap time, such as delay, the power supply switching circuit is simpler and more reliable in control logic.
  • The circuit is also less sensitive to process variations, further enhancing the device's reliability.


Original Abstract Submitted

Embodiments provide a power supply switching circuit, which generates a first control signal jointly by utilizing a first input signal and a first drive signal opposite in phase to a second control signal, and generates the second control signal jointly by utilizing a second input signal and a second drive signal opposite in phase to the first control signal, such that time (i.e., overlap time) required for simultaneously turning on or off a first output subcircuit and a second output subcircuit is greatly reduced or even eliminated, effective output of an output node is implemented, and reliability of a device is improved. Furthermore, compared with eliminating the overlap time by means of delay, eliminating the overlap time by means of the power supply switching circuit is simple and reliable in control logic and is insensitive to process, which further improves the reliability of the device.
