【Abstract】 An implementation of negative high-voltage charge pump used for single and low-voltage power flash memory is proposed in this paper. Based on the analysis of the traditional charge pump, referred to the working conditions and parameter requirements of Flash memory, a new structure of triple-well negative high-voltage charge pump without threshold loss is brought forward. The result of test (SMIC 0.22um Flash) is given at the last section.更多还原
