摘要
A negative voltage switch for use in flash memory. The switch has a control end and two voltage output ends, and includes two inverting units for transferring a positive voltage, two driving units for transferring a negative voltage, and two negative voltage pass-gate transistors for respectively transferring the negative voltage to the voltage outputs. Each inverting unit connects to a driving unit at a corresponding node, and each negative voltage pass-gate transistor connects to one of the nodes. According to a voltage at the control end, the switch turns on one inverting unit to transfer the positive voltage at the corresponding node, and the driving unit connected to the other node turns on to transfer the negative voltage to the corresponding negative voltage pass-gate transistor such that the negative voltage pass-gate transistor stops outputting the negative voltage at the other voltage output.
