1. A system for dynamically sharing power grids of a memory device, the memory device comprising a memory vault, a memory controller, and a processing element, the system comprising:
- a first power grid, a second power grid and a first switch;
a first power supply configured to provide power to the first power grid in a first component of the memory device, the first power grid directing power to internal points within the first component, the first component located on at least one of the memory vault, the memory controller, and the processing element;
a second power supply configured to provide power to the second power grid in a second component of the memory device, the second power grid directing power to internal points within the second component, the second component located on at least one of the memory vault, the memory controller, and the processing element, the second component different than the first component; and
a controller configured to dynamically change a state of the first switch that controls a sharing of power between the first power grid and the second power grid during a runtime of the memory device.

Abstract
According to one embodiment, a method for dynamically sharing power grids of a device includes providing power from a first power supply to a first power grid in a first component of the device. The method also includes providing power from a second power supply to a second power grid in a second component of the device and dynamically changing, by a controller, a state of a first switch that controls a sharing of power between the first power grid and the second power grid during a runtime of the device.

12. A system for dynamically sharing power grids of separate components of a memory device, the memory device comprising a memory vault, a memory controller, and a processing element, the system comprising:
-
a first power grid and a second power grid; a first power supply configured to provide power to the first power grid in a first component of the memory device, the first power grid directing power to internal points within the first component, the first component located on at least one of the memory vault, the memory controller, and the processing element; a second power supply configured to provide power to the second power grid in a second component, the second power grid directing power to internal points within the second component, the second component located on at least one of the memory vault, the memory controller, and the processing element, the second component different than the first component; and a controller configured to; determine an operation mode for the first power grid or the second power grid; determine a runtime parameter relating to power provided to the first power grid or relating to power provided to the second power grid; and dynamically control a sharing of power between the first power grid and the second power grid based on logic in a controller and at least one of;
the determined operation mode and the determined runtime parameter. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
