摘要: A method of testing a semiconductor device having a memory is disclosed. The method includes selecting a portion of the memory; testing the selected portion of the memory; designating the selected portion of the memory as a designated memory in response to an acceptable testing result; and storing data in the designated portion of the memory for retrieval at a later time. Provision for soft repair of the selected memory is made. Test data can be compressed before being stored in the designated memory.

摘要: A structure and method for identifying a physical location of a defect in a logic circuit based on a physical location of a logic latch having failing data. The logic circuit includes a plurality of logic latches, each having a predetermined physical location within the logic circuit. The logic latches are connected to devices adjacent the logic latches, such that the failing data in the logic latch indicates a failure of a device adjacent the logic latches.
