    摘要: A memory subsystem empirically tests performance parameters of I/O with a memory device. Based on the empirical testing, the memory subsystem can set the performance parameters specific to the system in which the memory subsystem is included. A test system performs the testing. For each of multiple different settings for multiple different I/O circuit parameters, the test system sets a value for each I/O circuit parameter, generates test traffic to stress test the memory device with the parameter value(s), and measures an operating margin for the I/O performance characteristic. The test system further executes a search function to determine values for each I/O circuit parameter at which the operating margin meets a minimum threshold and performance of at least one of the I/O circuit parameters is increased. The memory subsystem sets runtime values for the I/O circuit parameters based on the search function.

    摘要: A memory subsystem can test a memory device in situ, testing the performance of parameters of operation the device in the system it is built into during production. Thus, the system can detect the specific values that will work for one or more operating parameters for the memory device in actual runtime. A test component embedded in the memory subsystem can perform a stress test and identify specific bits or lines of memory that experience failure under one or more stresses. The system can then map out the failed bits or lines to prevent the bits/lines from being used in runtime of the system.

    摘要: A method for effecting an in-band reset of the physical layers of two agents interconnected through a link-based interconnection scheme. In accordance with one embodiment of the invention, a first of the two agents ceases its forwarded clock to initiate the in-band reset. Upon realization of the cessation, a second agent ceases its forwarded clock and proceeds to a reset state. The first agent then proceeds to a reset state. Subsequently, after waiting a specified period of time, both agents proceed with a re-initialization of the physical layer. In accordance with one embodiment of the invention, the re-initialization of the physical layer is effected without impacting other layers of the interconnection hierarchy.
