<p>SYSTEMS, CIRCUITS AND METHODS FOR ADAPTING WORD LINE (WL) PULSE WIDTHS USED IN MEMORY SYSTEMS (200) ARE DISCLOSED. ONE EMBODIMENT OF THE INVENTION IS DIRECTED TO AN APPARATUS COMPRISING A MEMORY SYSTEM (200). THE MEMORY SYSTEM (200) COMPRISES: A MEMORY (210) OPERATING ACCORDING TO A WORDLINE (WL) PULSE WITH AN ASSOCIATED WL PULSE WIDTH; A BUILT-IN SELF-TEST (BIST) UNIT (220) THAT INTERFACES WITH THE MEMORY (210), THE BIST UNIT (220) BEING CONFIGURED TO RUN A SELF-TEST OF THE INTERNAL FUNCTIONALITY OF THE MEMORY (210) AND PROVIDE A SIGNAL INDICATING IF THE MEMORY (210) PASSED OR FAILED THE SELF-TEST; AND AN ADAPTIVE WL CONTROL CIRCUIT THAT INTERFACES WITH THE BIST UNIT (220) AND THE MEMORY (210), THE ADAPTIVE WL CONTROL CIRCUIT BEING CONFIGURED TO ADJUST THE WL PULSE WIDTH OF THE MEMORY (2100 BASED ON THE SIGNAL PROVIDED BY THE BIST UNIT (220).</p> |
