    摘要: Data pin mapping and delay training techniques. Valid values are detected on a command/address (CA) bus at a memory device. A first part of the pattern (high phase) is transmitted via a first subset of data pins on the memory device in response to detecting values on the CA bus; a second part of the pattern (low phase) is transmitted via a second subset of data pins on the memory device in response to detecting values on the CA bus. Signals are sampled at the memory controller from the data pins while the CA pattern is being transmitted to obtain a first memory device's sample (high phase) and the second memory device's sample (low phase) by analyzing the first and the second subset of sampled data pins. The analysis combined with the knowledge of the transmitted pattern on the CA bus leads to finding the unknown data pins mapping. Varying the transmitted CA patterns and the resulting feedbacks sampled on memory controller data signals allows CA/CTRL/CLK signals delay training with and without priory data pins mapping knowledge.

    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 memory subsystem includes a test signal generator of a memory controller that generates a test data signal in response to the memory controller receiving a test transaction. The test transaction indicates one or more I/O operations to perform on an associated memory device. The test signal generator can generate data signals from various different pattern generators. The memory controller scheduler schedules the test data signal pattern, and sends it to the memory device. The memory device can then execute I/O operation(s) to implement the test transaction. The memory controller can read back data written to a specific address of the memory device and compare the read back data with expected data. When the read back data and the expected data do not match, the memory controller can record an error. The error can include the specific address of the error, the specific data, and/or encoded data.

    摘要: Circuitry to provide a supply voltage. A voltage regulator is coupled to receive a target reference signal. The voltage regulator generates a supply voltage (Vtt) and is coupled to receive the supply voltage as an input signal. An upper limit comparator receives an upper limit voltage signal that is higher than the target reference voltage signal and the supply voltage to generate a “too high” signal when the supply voltage exceeds an upper threshold. A lower limit comparator receives a lower limit voltage signal that is lower than the target reference voltage signal and the supply voltage to generate a “too low” signal when the supply voltage is below a lower threshold. A pull up current source is coupled to pull the supply voltage up in response to the too low signal. A pull down current source is coupled to pull the supply voltage down in response to the too high signal.

    摘要: A device with an I/O interface includes a replica clock distribution path matched to a clock distribution path of an unmatched receiver circuit. The device can monitor changes in delay in the replica path, and adjust delay in the real clock distribution path in response to the delay changes detected in the replica path. The receiver circuit includes a data path and a clock distribution network in an unmatched configuration. A ring oscillator circuit includes a replica clock distribution network matched to the real clock distribution network. Thus, delay changes detected for the replica clock distribution network indicates a change in delay in the real clock distribution network, which can be compensated accordingly.
