Patent ID: 8351265

Claim:
A flash memory device comprising: a first section including flash memory for storing data; and a second section configured to receive a supply voltage including: i) a first pumping circuit being configured to increase the supply voltage produced under control of at least a first oscillation signal having a first output and a second pumping circuit connected to the output of the first pumping circuit being configured to increase the supply voltage produced therefrom under control of at least a second oscillation signal, different from the first oscillation signal having a second output at a different and higher voltage that the first output, ii) first and second regulator circuits; and iii) first and second oscillators for providing the first and second oscillation signals respectively, the first regulator circuit coupled to the first pumping circuit output, the first oscillator configured to receive an outputted voltage of the first regulator circuit, the second regulator circuit coupled to the second pumping circuit output, and the second oscillator configured to receive an outputted voltage of the second regulator circuit.
