Abstract: A system-on-a-chip (“SoC”) in a computing device may be provided with a power delivery network (“PDN”) self-test to detect marginal PDN performance. In the self-test, a current surge may be generated on power supply connections of logic circuit blocks. Voltage monitors may measure voltage droop on the power supply connections responsive to the current surge. Voltage droop measurements may be compared with thresholds. An action, such as generation of an alert, may be performed if a voltage droop measurement exceeds a threshold.

Abstract: Systems and method are directed to reducing power consumption of a memory based on enabling partial page access. Based on system conditions such as operating frequency, access size for one or more memory access requests are determined. The access size is programmed in a mode register of the memory and one or more commands are issued for accessing the memory based on the programmed access size. Alternatively, the access sizes are specified within the one or more commands issued to the memory for accessing partial pages. Activating only the portion of a page corresponding to the partial page access reduces power consumption.

Abstract: Systems and method are directed to reducing power consumption and/or improving performance of a processing system comprising a processor subsystem and a memory subsystem. A variable length column command is used in place of a plurality of column commands directed to a same page of a memory bank of the memory subsystem. The variable length column command is provided to the memory subsystem based on a detection of a plurality of accesses directed to the same page.
