摘要:
An integrated circuit (IC) comprises a memory module that stores at least one of data and code. A memory repair database stores data relating to defective memory addresses. A memory control module detects defective memory locations in the memory module, locates redundant memory elements in the memory module, and stores information that associates memory addresses of the defective memory locations with the redundant memory elements in the memory repair database. Storing said information includes electrically altering at least one of a plurality of electrical fuses. A redundant memory decoder module receives the information and physically remaps the memory addresses to the redundant memory locations.
