This paper describes a defect-oriented analysis of 4 BIST tests that are used to test a commercial 6-port embedded SRAM. We will examine the realistic fault and defect coverages of these memory BIST tests. We also uncover the subtle effect that addressing order has on the coverage that a test can provide. In addition, we will show that the coverage that a test provides can vary from row to row depending on the addressing scheme.
