ABSTRACT:
A field effect transistor amplifier for use as on the output buffer for semiconductor memories including an electrically alterable element added to an active pull up configuration to allow conversion between active pull up and open drain nonvolatile configurations reversibly or irreversibly. A fusible element or P-N junction device is electrically alterable for irreversible configuration conversion and an amorphous material element is electrically alterable for reversible and irreversible configuration conversion.
