Benefits of technology

This patent describes a way to protect against leaks caused by electrical signals on electronic devices during normal operation. It suggests that if there are any issues or problems with certain parts of the device being used for communication, it can stop sending data through these areas instead of directly transmitting them over wires. Additionally, this technology helps improve the efficiency of power supply systems.

Problems solved by technology

The technical problem addressed by this patent is how to efficiently manage power usage during idle modes without sacrificing performance in normal operation modes that require more power.

Abstract

A multi-threshold CMOS system and method controls a state of respective blocks individually. Each block includes a logic circuit having a logic transistor and a control transistor connected between the logic circuit and a power line connected to one of a ground and a power source. The control transistor has a higher threshold than the logic transistor. The blocks are controlled by generating an individual block ON/OFF signal for each block, generating an individual control signal in response to the individual block ON/OFF signal, supplying the individual control signal to the control transistor and controlling voltage supply to the logic circuit within each block in accordance with the individual control signal.
