Abstract :
In this paper we present a circuit scheme capable of providing the supply voltage for the final stages of the row decoder in a 5-V-only flash memory. The circuit is capable of delivering the positive (5 V or 10.5 V) or negative (-12 V) voltage required in read, program and erase operations, respectively. The high positive and the negative voltages are obtained with voltage multipliers based on the charge-pump approach. A single line is used to supply the final stages of the row decoder. The topology proposed is suitable for single-well processes
