L'augmentation du temps de test des DRAM intégrées (e-DRAM) est l'un des problèmes clés du test des dispositifs System-on-Chip (SOC). Cet article propose de mettre la fonction d'analyse de réparation sur puce sous le nom de Built In Self Repair (BISR). Le BISR est effectué à 166 MHz à la vitesse de l'e-DRAM en utilisant un équipement de test automatique (ATE) à faible coût. La surface du BISR est de 1.7 mm2. L'utilisation du formulaire de table de stockage des erreurs contribue à réaliser une pénalité de petite zone pour la fonction d'analyse des réparations. La durée du test de la fonction e-DRAM par BISR était d'environ 20 % inférieure à celle de la méthode conventionnelle de test au niveau des tranches. De plus, des échantillons représentatifs sont produits pour confirmer la capacité d’analyse des réparations. Les résultats montrent que tous les échantillons sont réellement réparés grâce aux informations de réparation générées par BISR.

Abstract: The increase of test time of embedded DRAMs (e-DRAM) is one of the key issues of System-on-chip (SOC) device test. This paper proposes to put the repair analysis function on chip as Built In Self Repair (BISR). BISR is performed at 166 MHz as at-speed of e-DRAM with using low cost automatic test equipment (ATE). The area of the BISR is 1.7 mm2. Using error storage table form contributes to realize small area penalty of repair analysis function. e-DRAM function test time by BISR was about 20% less than the conventional method at wafer level testing. Moreover, representative samples are produced to confirm repair analysis ability. The results show that all of the samples are actually repaired by repair information generated by BISR.
