Method and apparatus for a dual power supply to embedded non-volatile memory

An embedded non-volatile memory being driven at an external voltage level and at an regulated voltage level, the external voltage level higher than the regulated voltage level, comprising:

• a charge pump configured to receive the external voltage level and generate a high voltage level, the high voltage level higher than the external voltage level;
• a memory control circuit coupled to the charge pump and configured to receive the external voltage level and the high voltage level, and further configured to select between and provide the external and the high voltage levels;
• a memory array, having a word line and a bit line, coupled to the memory control circuit and configured to store data and to receive the external and high voltage levels at the word line, and to receive the high voltage levels at the bit line;
• a word line driver coupled to the memory array and configured to provide the external and high voltage levels to the word line;
• a bit line selector coupled to the memory array and configured to select the bit line and receive the high, external, and regulated voltage levels;
• and
• a bit line driver coupled to the bit line selector and configured to provide the external and regulated voltage levels to the bit line selector.
