Abstract: An expandable memory system that enables a fixed signaling bandwidth to be configurably re-allocated among dedicated memory channels. Memory channels having progressively reduced widths are dedicated to respective memory sockets, thus enabling point-to-point signaling with respect to each memory socket without signal-compromising traversal of unloaded sockets or costly replication of a full-width memory channel for each socket.

Abstract: The reliability of a data communication link may be analyzed and otherwise maintained by collecting a two-dimensional array representing a functional data eye, and using a convolutional neural network to determine a score of the functional data eye. The determined score may be compared with a threshold, and an action may be initiated based on the result of the comparison.

Abstract: A method performed by a machine learning system includes generating a set of reward values based on a set of parameter values selected by a machine learning system, each reward value of the set of reward values corresponding to a parameter value of the set of parameter values programmed at a device. The method also includes determining a reward function for maximizing a reward corresponding to a set of parameters of the device based on the set of reward values. The method further includes tuning a parameter of the set of parameters based on the reward function.

Abstract: Certain aspects of the present disclosure generally relate to memory training. An example method generally includes assigning each of a plurality of data channels of a memory device to at least one processor, performing memory tests, in parallel, on the plurality of data channels by at least in part performing read and write operations on at least two or more of the plurality of data channels in parallel using the at least one processor, and determining a setting for one or more memory interface parameters associated with the memory device relative to a data eye for each of the plurality of data channels determined based on the memory tests.

Abstract: An integrated-circuit buffer component includes a control-side data interface configurably coupled to first and second memory-side data interfaces via internal conductors, the first data interface having twice as many input/output (I/O) transceivers as the second data interface. In a first memory system configuration in which only the first data interface is coupled to a memory module, steering circuitry couples all the internal data conductors exclusively to the I/O transceivers of the first data interface. In a second memory system configuration in which the first and second data interfaces are coupled to respective memory modules, the steering circuitry couples a first half of the internal data conductors exclusively to the I/O transceivers of the second data interface while a second half of the internal data conductors remains exclusively coupled to half the I/O transceivers of the first data interface.

Abstract: In calibrating the phase skew between an SDRAM data strobe (“DQS”) signal and data (“DQ”) signal in a device, the data signal driver circuit impedance is adjusted to impair impedance matching on the DQ signal channel while system-level memory tests are performed. The phase skew is stepped through a range during the memory tests, and an error count is determined for each test. The memory tests may emulate mission-mode operation of the device. Following the memory tests, an optimal phase skew corresponding to a lowest error count is determined. The DQS signal may be delayed with respect to the DQ signals by a value corresponding to the optimal phase skew in subsequent mission-mode operation of the device.
