Abstract
In this paper a complete analysis of spot defects in industrial SRAMs will be presented. All possible defects are simulated, and the resulting electrical faults are transformed into functional fault models. The existence of the usually used theoretical memory fault models will be verified and new ones will be presented. Finally, a new march test detecting all realistic faults, with a test length of 14n, will be introduced, and its fault coverage is compared with other known tests.
