Reprogrammable Memory Repair

Abstract

Aspects of reprogrammable memory repair are disclosed. For example, blown-fuse data may be configured to prevent access to faulty locations within a memory. However, the blown-fuse data may include incorrect faulty locations or additional faulty locations may be determined after the fuse data was blown. A repair-word may be applied to invalidate a specified word stored at a faulty location. The repair-word modifies a memory subsystem portion of the word, a specified memory of the memory subsystem portion of the word, or the entire specified word itself to prevent access of the memory location and redirect access to a redundant location within the memory. Alternatively, the repair-word may be configured to erase, invalidate, or modify a specified word stored within fuse data. In another aspect, automatic test equipment may be configured to modify a single entry of the fuse data stored within a shadow storage.

Dependencies are inferred from the claim text.
