发明名称 Dynamic repair of redundant memory array
摘要 A circuit arrangement and method of dynamically repairing a redundant memory array utilize dynamically-determined repair information, generated from a memory test performed on the redundant memory array, along with persistently-stored repair information to repair the redundant memory array. In one implementation, for example, the persistent repair information is generated during manufacture to repair manufacturing defects in the array, with the dynamic repair information generated during a power-on reset of the array to address any additional faults arising after initial manufacture and repair of the array. Furthermore, repair of dynamically-determined errors may utilize otherwise unused redundant memory cells in a redundant memory array, thus minimizing the additional circuitry required to implement dynamic repair functionality with an array.
