Substrate voltage control circuit for a flash memory |
摘要 |
A substrate voltage control circuit is used to apply bias voltage to a substrate or a well of a semiconductor memory such as a flash memory. The substrate voltage control circuits do not use any depletion type transistors. Therefore, the area occupied by the transistors for the circuit is small. |
