Abstract:
1. A controller integrated circuit for a non-volatile memory system, comprising: a voltage regulator connectable to a power supply to generate and supply therefrom a first regulated voltage to a first section of the controller circuit, wherein the voltage regulator adjusts the level of the first regulated voltage in response to a control signal; a voltage detector connected to receive a reference voltage and an internal voltage level from the first section of the controller circuit and determine within which of a plurality of voltage ranges an average of the internal voltage level of the first section falls while in operation and generate therefrom a first signal indicative thereof; and a core processing section including logic circuitry connected to supply the control signal to the voltage regulator and connected to receive the first signal and in response thereto trim the value of the control signal.
