Abstract

LA INVENCION CONCIERNE A LOS PROCESOS DE PROGRAMACION DE LAS MEMORIAS DEL TIPO CON PROTECCION POR FUSIBLE EN PARTICULAR DE LAS UTILIZADAS EN LAS TERJETAS "ELECTRONICAS". CONSISTE EN APLICAR LA TENSION DE PERFORACION DURANTE UNA DURACION (204) MUY SUPERIOR A LA CORRIENTEMENTE UTILIZADA Y EN LIMITAR LA CORRIENTE (206) A UN VALOR TAMBIEN MUY SUPERIOR AL HABITUAL, TIPICAMENTE, SE COGE 100 MS Y 2 A. UNOS MEDIOS INFORMATICOS PROGRAMABLES (102) PERMITEN REGULAR ESTOS VALORES Y PROCEDER A UNOS TESTS PREVIOS. PERMITE EVITAR LA RECONSTITUCION DEL FUSIBLE PERFORADO Y LOS ERRORES QUE SE DERIVAN.
