Abstract
A CPU-based systemand method for testing embedded memory. The technique employs the on-chip CPUitself to test the embedded memoryAn assembly code program is loaded into the device under test (DUT)to test the memories, determine a repair solution, and write out the repair solution and raw failure information to the tester for defect analysis. The test is driven by an external programmable clock that is provided by the tester to allow the DUTto run up to its maximum input clock rate in order to maximize throughput. The test is not dependent on the pattern rate of the tester.
