A shared built-in self-repair analysis for multiple embedded memories

摘要

A Shared Built-in Self-Repair Analysis scheme (Shared-BISA) for multiple embedded memory cores in the SOC is proposed to realize minimum area penalty independent of the number of embedded memory cores. A compact re-configurable CAM array in the BISA circuitry realizes a flexible redundancy analysis structure to cope with various memory core and redundancy structures, and a high-speed operation up to 500MHz.
