ABSTRACT:
A method and apparatus for regulating voltages in semiconductor devices. Trim bits are stored in a trim flash array, where the trim bits define a voltage value and where the voltage value is accessible once a control signal representing a word line signal is provided to the trim flash array reaches a selected voltage level. A refresh signal is provided to a voltage regulator in response to the control signal reaching the selected level, causing the voltage regulator to change its regulation value to that defined by the trim bits. A signal at a voltage level represented by the voltage value is provided to a memory array that is accessed based on the provided signal.
