MEMORY DEVICE WITH SECURE TEST MODE AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for achieving the security of a memory device in a testing mode.SOLUTION: A method in a memory device that operates in a testing mode includes the steps of: receiving a vector to be written to the memory device; writing the vector to the memory device only if the vector belongs to a predefined set of test vectors; and converting the vector to one of the test vectors and writing the converted vector to the memory device if the vector does not belong to the set of the test vectors.SELECTED DRAWING: Figure 2
