Substrate bias switching unit for a low power processor

The feature of the present invention consists in: a processor main circuit for executing program instruction strings on a processor chip; a substrate bias switching unit for switching voltages of substrate biases applied to a substrate of the processor main circuit; and an operation mode control unit for controlling, in response to the execution of an instruction to proceed to a stand-by mode in the processor main circuit, the substrate bias switching unit in such a way that the biases are switched over to voltages for the stand-by mode, and for controlling, in response to an interruption of the stand-by release from the outside, the substrate bias switching unit in such a way that the biases are switched over to voltages for a normal mode, and also for releasing, after the bias voltages switched thereto have been stabilized, the stand-by of the processor main circuit to restart the operation.

Preparation method of MPS diode and MPS diode

The invention belongs to the field of semiconductors, and provides a preparation method of an MPS diode and the MPS diode, and the method comprises the following steps: forming a second epitaxial layer on the upper surface of a first epitaxial layer; a third epitaxial layer is formed on the upper surface of the second epitaxial layer, the doping concentration of the third epitaxial layer is smaller than that of the second epitaxial layer, and the doping concentration of the second epitaxial layer is larger than that of the first epitaxial layer; a drift doping region is formed in the third epitaxial layer, and the depth of the drift doping region is larger than the thickness of the third epitaxial layer; and forming an anode metal layer on the upper surfaces of the third epitaxial layer and the drift doping region, and forming a cathode metal layer on the lower surface of the first epitaxial layer. When the MPS diode is turned on in the forward direction, the resistivity of the MPS diode is low, when the MPS diode is turned on in the reverse direction, the second epitaxial layer and the third epitaxial layer are in a high-resistance state, the surface electric field intensity distribution below the anode metal layer can be reduced, and the problem that the leakage current of the MPS is large is solved.

Operating method of the memory

A method of programming the storage comprises setting the storage to an initial state of a first grid threshold voltage, performing a processing sequence including: applying a voltage bias between the grid and the first junction region to cause electric hole to migrate towards and be retained in the trapping layer, and evaluating a read current generated in response to the voltage bias to determine whether a second grid threshold voltage is reached, wherein the second grid threshold voltage is lower than the first grid threshold voltage. The processing sequence is repeated a number of times by varying one or more time the voltage bias between the grid and the first junction region until the second grid threshold voltage is reached and the storage is in a program state.
