General purpose, non-volatile reprogrammable switch

An integrated circuit having first and second circuit nodes and a programmable interconnect, said programmable interconnect capable of connecting said circuit nodes responsive to a programmed state of said programmable interconnect, said programmable interconnect comprising

• a first MOS transistor having first and second source/drains connected to the first and second circuit nodes respectively, and a floating gate;
• and
• means for charging and discharging said floating gate, said charging and discharging means having no connection to said first and second source/drains of said first MOS transistor, said first MOS transistor remaining on during normal operation of said integrated circuit unless said floating gate has been charged and said first MOS transistor remaining off during normal operation of said integrated circuit unless said floating gate has been discharged.
