Built-In Testing of Memory Using an On-Chip Compact Testing Scheme
Kinoshita, Saluja · IEEE Transactions on Computers · 1986
In this paper we study the problem of testing RAM. A new fault model, which encompasses the existing fault models, is proposed. We then propose a scheme of testing faults from the new fault model using built-in testing techniques. We introduce concept of p-hard and determine the complexity of the extra hardware required for built-in self-testing on our hardness scale. A novel approach using microcoded ROM for implementation of built-in testing is also proposed and its complexity is determined.
