Abstract
A built-in self test (BIST) method and system for testing a memory included on an integrated circuit includes activating a component of the integrated circuit, partitioning the memory into a first part for use by non-BIST components and second part for BIST, and executing BIST on the second part of the memory while the component is operating. While the BIST is executing, the non-BIST components can access the first part of the memory and perform normal functional operations. The BIST method and system finds memory faults that are related to an I-R voltage drop due to the physical placement of the memory relative to power supply sources.
