Abstract

Die erfindungsgemäße Schaltungsanordnung erlaubt die Bereitstellung einer internen Versorgungsspannung für integrierte Schaltungen auf zwei unterschiedlichen, jeweils konstanten Niveaus. Die Auswahl der Niveaus erfolgt allein durch die Höhe der externen Versorgungsspannung. Dadurch ist es möglich, zwischen einem Betriebsmodus, bei dem die interne Versorgungsspannung auf dem betriebsüblichen Wert liegt, und einem Testmodus, bei dem die interne Versorgungsspannung auf einem erhöhten Wert liegt, umzuschalten. Die Erfindung findet Anwendung insbesondere bei Halbleiterspeichern.
