IC encryption method capable of achieving ultralow standby power consumption

Abstract

The invention discloses an IC encryption method capable of achieving ultralow standby power consumption, which comprises a first circuit, a second circuit and a key, wherein the first circuit comprises a standby circuit, a core circuit and an Eflash macro circuit; the standby circuit comprises a PMOS tube and an NMOS tube; the core circuit comprises a calibrator and a register; the PMOS tube is electrically connected with the calibrator; the NMOS tube is electrically connected with the register; when for connection of the first circuit, the calibrator judges whether the permission exists or not according to a read authorization code; when no permission, the PMOS tube is connected with the first circuit for calibration; when the permission exists, the NMOS tube is connected with the first circuit, provided with a corresponding register and enters a low-power-consumption standby state; and the external of the second circuit is further connected with a key. According to the IC encryptionmethod capable of achieving the ultralow standby power consumption, the IC can be encrypted to increase the security; meanwhile, the problem of standby power consumption is solved, and the applicationsurface is expanded.

Description

technical field [0001] The invention belongs to the technical field of integrated circuits, and in particular relates to an IC encryption method capable of realizing ultra-low power consumption standby. Background technique [0002] An integrated circuit (integrated circuit, called an integrated circuit in Hong Kong and Taiwan) is a microelectronic device or component. Using a certain process, the transistors, diodes, resistors, capacitors, inductors and other components required in a circuit are interconnected together, fabricated on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a tube. Inside the shell, it becomes a microstructure with the required circuit functions; all the components in it have been structurally integrated, so that the electronic components have taken a big step towards miniaturization, low power consumption and high reliability. It is represented by the letter "ic" (also with the text symbol "n", etc.) in ...
