摘要: An integrated programmable logic device (PLD) includes flash EPROM storage transistors. The PLD includes a multiplexor that selectively provides program, erase, or verify voltages to the storage transistors. The program, erase, and verify voltages may be supplied using external power supplies or may be generated internally by on-chip charge-pump generators. A configurable memory on the PLD is used to adjust the output voltages from each of the on-chip charge-pump generators.
