SHARED FUSE WRAPPER ARCHITECTURE FOR MEMORY REPAIR

摘要

A memory repair mechanism for the memories clustered across the multiple power domains and can be switched on and off independent of each other, thereby enabling low power operation. Enhancements in the shared Fuse Wrapper Architecture enable sharing of a plurality of parallel links connecting the memory blocks of each power domains to the Shared Fuse Wrapper architecture.

主权项

1. A method for memory repair across multiple power domains, said method comprising:
determining defective memory locations and corresponding repair data for each memory block in each power domain; encoding the address and the repair data of each defective memory location; storing the encoded address and repair data obtained by incremental encoding across power domains; decoding the encoded the address and the repair data during functional operation; and repairing the defective memory locations.
