  • Publication number: 20250094264
    Abstract: Various embodiments include methods and devices for implementing a scan dump of memory subsystem cores. Embodiments may include enabling a scan dump path of the memory subsystem during a computing device crash reset flow, the scan dump path comprising at least one memory controller having at least one scan dump logic module, a scan dump network on chip (NoC) module, and at least one scan dump data bus connecting the at least one scan dump logic module and the scan dump NoC, and initializing a scan mode for a memory path of the memory subsystem and for a low power memory path of the memory subsystem.

  • Publication number: 20210021193
    Abstract: The disclosed technology can be used to convert direct-current voltage and current from an input to a different or the same voltage and current at an output. One example direct-current to direct-current (DC-DC) power converter includes a first switch connected between a source voltage and a first side of an inductor, a second switch connected between the first side of the inductor and a ground, a third switch connected between a second side of the inductor and the ground, and a fourth switch connected between the second side of the inductor and a capacitor. The power converter may further include a comparator configured to compare an output voltage at the capacitor to a threshold voltage and based on the result of the comparison selectively activate or deactivate the first, second, third, and fourth switches in a power cycle.
