Abstract: A novel row decoder/driver circuit in which switched bias voltages are applied to the bulk regions in order to minimize the maximum voltage differential appearing across transistor devices. This allows the decoder/driver circuit to be conveniently fabricated and designed to allow normal transistors rather than more complex and expensive high voltage transistors, to form the row decoder/driver. The bulk regions containing the pull-up and pull-down transistors are biased by voltages which are switched during erasure depending on whether the row line is selected or deselected in order to assure that excessive voltages do not appear across based upon the voltage levels applied to the transistors.
