Examples of the present disclosure generally relate to integrated circuits, such as a system-on-chip (SoC), that include a memory subsystem. In some examples, an integrated circuit includes a first master circuit in a first power domain on a chip; a second master circuit in a second power domain on the chip; and a first memory controller in a third power domain on the chip. The first master circuit and the second master circuit each are configured to access memory via the first memory controller. The first power domain and the second power domain each are separate and independent from the third power domain.

Disclosed herein are a vehicle or other system battery with a self-contained backup capability and a method for providing power to a vehicle using the vehicle or other system battery with a self-contained backup capability. In one aspect, the vehicle battery comprises, a main battery portion, a backup battery portion, and a control device for selectively communicating a transfer of energy from the backup battery portion to the main battery portion when a voltage level or other health indicator of the main battery portion is determined to be below a reference voltage threshold, wherein the main battery portion and backup battery portion are each re-chargeable via an alternator of the vehicle when the control device communicates the transfer of energy between the main battery portion and the backup battery portion.

A processing device in a memory sub-system detects a preemptive power loss condition in the memory sub-system and, in response, causes operations of a local media controller associated with a memory device in the memory sub-system to be suspended, wherein responsive to being suspended, the local media controller to perform power loss handling operations to complete a subset of a plurality of pending memory access operations, and wherein to perform the power loss handling operations, the local media controller to complete the subset of the plurality of pending memory access operations for which an acknowledgment signal has been sent to a requestor. The processing device further detects a full power loss and restore condition in the memory sub-system, responsive to detecting the full power loss and restore condition, initializes the memory device and causes operations of the local media controller to resume.

A combined data/power coupling device includes a chassis having first and second powering device connectors and a powered device connector each coupled to a data/power coupling subsystem. The data/power coupling subsystem configures each of the first and second powering device connectors to receive power from at least one powering device, configures the first powering device connector to receive data from the at least one powering device, and provides data and power received via the first powering device connector to a powered device via the powered device connector. When the data/power coupling subsystem determines that data and power are not available via the first powering device connector, it configures the second powering device connector to receive data from the at least one powering device, and provides data and power received via the second powering device connector to the powered device via the powered device connector.

One or more sampling parameters of an application associated with a downstream voltage regulator may be determined. A power supply rejection ratio (“PSRR”) and a switching frequency of an upstream voltage regulator may be dynamically adjusted based on the sampling parameters of the application associated with the downstream voltage regulator. The sampling parameters may include a noise level and a workload of the selected application.

An Internet of Things device is herein disclosed. The Internet of Things device comprises a communications module having circuitry to communicatively connect to a computer network, a memory operable to store data, a processor coupled to the memory and the communications module and operable to execute instructions stored in the memory, and an activity module, including at least one of a sensor and a control device. The activity module operates under control of the processor to perform a designated activity with at least one of the sensor and the control device. The activity module further communicates on the computer network via the communications module. The processor curtails a volume of communication of the communications module on the computer network if a measured value of a system parameter exceeds a threshold value.
