Beschreibung
Zusammenfassung:	A one-time programmable (OTP) latch circuit can include a single OTP device capable of storing a logic value in a nonvolatile fashion, or only two OTP devices in the event redundancy is desired. A latch section can latch a data value based on a comparison between a current drawn according to the one OTP device, and a reference current generated without and OTP device. An OTP device can include a gate oxide antifuse (GOAF) device. L'invention concerne un circuit de verrouillage à programmation unique (OTP) qui peut comprendre un seul dispositif OTP capable de stocker une valeur logique d'une façon non volatile, ou seulement deux dispositifs OTP au cas où une redondance est souhaitée. Une section de verrouillage peut verrouiller une valeur de données sur la base d'une comparaison entre un courant tiré selon le dispositif OTP, et un courant de référence généré sans le dispositif OTP. Un dispositif OTP peut comprendre un dispositif antifusible à oxyde de grille (GOAF).
