    摘要: A method and apparatus for automated calibration of I/O over a multi-variable eye window is provided. A transmitter may conduct data transmissions to a receiver of an integrated circuit (IC) over a plurality of signal lines. The data transmissions may be conducted according to a certain parameters or sets of parameters. Parameters may include voltage levels at which signals are transmitted or timing delays. The receiver may determine whether the correct data value was received over each signal line. The results may be recorded in a storage mechanism in the same IC as the receiver. The storage mechanism may, for each signal line, store a pass/fail result corresponding to the particular parameters for the data transmission. The system may select the parameters which subsequent transmissions are to be conducted over each of the plurality of signal lines from the storage mechanism.

    摘要: A system and method for increasing the yield of integrated circuits containing memory partitions the memory into regions and then independently tests each region to determine which, if any, of the memory regions contain one or more memory failures. The test results are stored for later retrieval. Prior to using the memory, software retrieves the test results and uses only the memory sections that contain no memory failures. A consequence of this approach is that integrated circuits containing memory that would have been discarded for containing memory failures now may be used. This approach also does not significantly impact die area.
