Question

4.(15') Memory fault model is very complex due to various failure mechanisms. Please enumerate the subcategories for memory coupling faults. For each subcategory, you only need to list the name of the fault, acronym, and notations. Do not write any explanation for them. For example, you can just list the inversion coupling fault entry as below without any explanation: inversion coupling faults (CFin): <T;I>,<t;I>
