Title (EN) COLUMN ADDRESS STROBE WRITE LATENCY (CWL) CALIBRATION IN A MEMORY SYSTEM
(FR) ÉTALONNAGE DU RETARD D'ÉCRITURE POUR TEMPS D'ACCÈS À UNE COLONNE DANS UN SYSTÈME DE MÉMOIRE
Abstract: front page image
(EN)Column address strobe write latency (CWL) calibration including a method for calibrating a memory system. The method includes entering a test mode at a memory device and measuring a CWL at the memory device. A difference between the measured CWL and a programmed CWL is calculated. The calculated difference is transmitted to a memory controller that uses the calculated difference for adjusting a timing delay to match the measured CWL.
(FR)La présente invention concerne l'étalonnage du retard d'écriture pour temps d'accès à une colonne ou "CWL" (Column adress strobe Write Latency) mettant en œuvre un procédé d'étalonnage d'un système de mémoire. Ce procédé consiste à faire passer en mode de test un dispositif de mémoire et à mesurer un CWL du dispositif de mémoire. On calcule ensuite un écart entre le CWL mesuré et un CWL programmé. La différence calculée est transmise à un contrôleur de mémoire qui se sert de la différence calculée pour ajuster un retard de synchronisation de façon à l'adapter au CWL mesuré.
