Method for classifying electronic devices
First Claim
Patent Images
1. A method for classifying an electronic device as being a first device type or a second device type, the device types each being contained in a package having the same number of terminals, the method comprising the acts of:
- identifying at least one target terminal which is used by the second device type and unused by the first device type;
testing the at least one target terminal; and
designating the device type based upon the results of the testing act.

Abstract
A method for classifying a device as being a first device type or a second device type, wherein the first and second device types are each contained a package which has a plurality of terminals. The method includes identifying at least one target terminal, testing the target terminal, and classifying the device based upon the testing act.

6. A method for classifying a component as a first type memory device having at least one input/output or a second type of memory device having a greater number of input/outputs, both types of memory devices being contained in packages having the same package style, the first and second type memory devices including the same member of terminals, the method comprising;
-
identifying at least one terminal coupled to at least one input/output which is present in the second type of memory device but not present in the first type of memory device; and checking continuity on the at least one terminal. - View Dependent Claims (7, 8, 9, 10)

11. A method for classifying a component as a first type memory device having at least one input/output or a second type of memory device having a greater number of input/outputs, both types of memory devices being contained in packages having the same package style, the first and second memory devices including the same number of terminals, the method comprising:
-
identifying at least one terminal coupled to at least one input/output which is present in the second memory device type but not present in the first memory device type;
checking continuity on the at least one terminalperforming a functional test which a properly functioning component of the first memory device type will pass but which a properly functioning component of the second memory device type will fail.

18. A method for classifying an electronic device as being a first device type or a second device type, the device types each being contained in a package having the same number of terminals, the method comprising:
-
identifying at least one target terminal; testing the at least one target terminal; designating the device type based upon the results of the testing act; and functionally testing the device, wherein the functional test comprises a test which a properly functioning device of the first device type will pass but which a properly functioning device of the second device type will fail. - View Dependent Claims (19, 20, 21)
