ABSTRACT:
A testing method for semiconductor memory that selects memory cells adjacent to the periphery of the memory array and to a memory twist. These memory cells are subjected to a more demanding test voltage and write recovery time to further stress the memory cells and reveal weak or marginally good memory cells.
