Abstract
A wordline driver for a wordline in an integrated programmable logic device (PLD) having flash memory cells. The wordline driver includes an input terminal that accepts a binary wordline input signal, a pass gate coupled to the input terminal and to a mode-control terminal, and an inverter that receives an input from the pass gate or the mode-control terminal, depending on the operating mode of the PLD. The output signal from the inverter is coupled to a multiplexer that selects between that output and a signal from a voltage supply, the signal selected depending on the operating mode of the PLD. The multiplexer outputs the selected signal to the wordline of the PLD.
