Abstract: A memory system including a memory controller with channel interfaces connecting memory groups via channels. Each channel interface communicates control, address and/or data (CAD) signals to a channel-connected memory group synchronously with a slave clock derived from an input clock. The various slave clocks being uniquely generated by application of channel interface specific phase/frequency modulation or temporal delay, such that the respective CAD signals are characterized by skewed transition timing.

Abstract: Methods and systems are provided for providing passive boost pressure monitoring for slow response with higher confidence. A response time of a boost pressure feedback control loop following a boost pressure deviation that is triggered by either system disturbances or operator torque demand is monitored. Slow boost behavior is correlated with boost control degradation affecting drivability and emissions.

Abstract: Methods and systems are provided for detecting a missing exhaust catalyst based on water adsorption and related exothermic temperature rise by the catalyst. In one example, a method may include indicating an exhaust catalyst missing in response to an estimated exhaust temperature profile being different from an expected exhaust temperature profile. The estimated exhaust temperature profile may be based on exhaust temperature upstream and downstream of the catalyst.

Abstract: Provided are a memory device and a memory system including the same. The memory device may include a first memory rank including at least one first memory chip, a memory controller configured to provide a command to the first memory rank, at least one data buffer configured to buffer data input to the at least one first memory chip or being output from the at least one first memory chip, and a second memory rank connected to the first memory rank and comprising at least one second memory chip. The first memory rank may provide training data and a data strobe signal to the second memory rank based on a data training command from the memory controller without the training data and the data strobe signal passing through the data buffer. The second memory rank may determine a delay of the data strobe signal based on the training data being detected by the second memory rank.

Abstract: Methods and systems are provided for detecting NOx sensor degradation based on results from a NOx sensor self-diagnostic (SD) test performed after a key-off event. In one example, a method may comprise waiting a duration to perform a SD test of a NOx sensor after a key-off event until engine operating conditions stabilize and reach a set of qualifying conditions. One or more SD tests may be performed after waiting the duration, but outputs generated under conditions where one or more of a temperature at the sensor is greater than a threshold, and an oxygen concentration is outside a threshold range, may be excluded when determining whether or not the NOx sensor is degraded.

Abstract: Methods and systems are provided for detecting NOx sensor degradation based on results from a NOx sensor self-diagnostic (SD) test. In one example, a method may comprise: determining that a nitrogen oxide (NOx) sensor is degraded if outputs received from the sensor via a CAN bus during a self-diagnostic test are outside a threshold range. Additionally, only outputs received from the sensor during a self-diagnostic (SD) test performed after a first completed SD test after a key-off event, where the outputs are generated under conditions where a temperature at the sensor is less than a threshold, and an oxygen concentration is within a threshold range may be used to determine if the sensor is degraded.
