Abstract:
A pumped voltage supply circuit for a semiconductor device operable in an an idle mode and in an active mode and having an input terminal for receiving a supply voltage, comprising:a voltage regulator for generating a regulated supply voltage; a charge pump for generating a pumped voltage greater than said supply voltage; a multiplexer having a first input for receiving said pumped voltage and a second input for receiving said regulated supply voltage, said multiplexer further having a select signal input and an output; a network coupled to said multiplexer output for distributing said pumped voltage to operational elements of said semiconductor device; wherein said multiplexer is responsive to a select signal applied to said select signal input to apply said regulated supply voltage to said multiplexer output when said device is operating in said idle mode and to apply said pumped voltage to said multiplexer output when said device is operating in said active mode.
