Patent ID: 6845476

Claim:
A method for testing a non-volatile memory, comprising the following steps: (a) preparing a first type correlation sample and a second type correlation sample, wherein the first type correlation sample is a non-volatile memory written with a code assigned by a client and a particular pin thereof is cut, and the second type correlation sample is a non-volatile memory which has been verified; (b) after restarting a testing machine, executing an open/short test for the particular pin of the first type correlation sample and the second type correlation sample, if the particular pin is opened, proceeding to step (c), otherwise, proceeding to step (d); (c) comparing the code of the first correlation sample with a code retrieved from a controlling program of the testing machine; if identical, the code retrieved by the controlling program is correct; otherwise, the code retrieved by the controlling program is incorrect; and (d) executing a predetermined test for the second correlation sample, if it is affirmative, the setting of the testing machine is correct; otherwise, the setting of the testing machine is incorrect.
