Claim Text:
1. An oscillation device, comprising: at least one non-volatile memory; a voltage generator, comprising a current source for providing a current flowing through the at least one non-volatile memory, for generating a bias voltage by using a non-volatile resistance of the at least one non-volatile memory; and a voltage-controlled oscillation (VCO) circuit, coupled to the voltage generator and configured to generate a corresponding oscillation frequency based on the bias voltage, wherein the non-volatile resistance of the at least one non-volatile memory is set independently from the current provided by the current source to adjust the bias voltage, wherein the non-volatile memory is located in the voltage generator, a first terminal and a second terminal of the non-volatile memory are respectively coupled to the current source and a low-level voltage, wherein the non-volatile memory comprises at least one resistive non-volatile memory (RNVM) cell coupled between the first terminal and the second terminal of the non-volatile memory so as to provide the non-volatile resistance, wherein the first terminal of the non-volatile memory provides the bias voltage, wherein the voltage generator further comprises:
