Abstract
A method, apparatus, and system are described in which a memory controller may have two or more registers to create and track zones of memory in a volatile memory device. The memory controller controls a power consumption state of a first zone of memory in the volatile memory device and a second zone of memory within the first volatile memory device on an individual basis; and one or more memory arrays contained within the first volatile memory device.
Claims21
An apparatus, comprising
- a memory controller having two or more registers to create and track zones of memory formed within a volatile memory device, wherein the memory controller to control a power consumption state of a first zone of memory in the volatile memory device and a power consumption state of a second zone of memory in the volatile memory device on an individual basis, wherein the power consumption state of the first memory zone of the volatile memory device is different from the power consumption state of the second memory zone of the volatile memory device;
- and
- one or more memory arrays contained within the volatile memory device.
A method, comprising:
- creating zones of memory in a first system volatile memory device that can be individually controlled to transition from a first power consumption state to a second power consumption state, wherein the first system volatile memory device includes one or more memory arrays;
- transitioning a first memory zone in the first system volatile memory device from the first power consumption state to the second power consumption state;
- and
- transitioning a second memory zone in the first system volatile memory device from the second power consumption state to the first power consumption state.
A system comprising
- a volatile memory device having one or more memory arrays contained within the volatile memory device;
- and
- a controller coupled to the volatile memory device;
- wherein the controller to create zones of memory in the volatile memory device that can be individually controlled to transition from a first power consumption state to a second power consumption state, wherein the power consumption state of the first memory zone of the volatile memory device is different from the power consumption state of the second memory zone of the volatile memory device;
- and
- a battery power supply to power the volatile memory device and the controller.
A machine-readable medium that provides instructions, which when executed by a machine, cause the machine to perform, operations:
- creating zones of memory formed in a first system volatile memory device that can be individually controlled to transition from a first power consumption state to a second power consumption state, wherein the first system volatile memory includes one or more memory arrays;
- transitioning a first memory zone in the first system volatile memory device from the first power consumption state to the second power consumption state;
- and
- transitioning a second memory zone in the first system volatile memory device from the second power consumption state to the first power consumption state.
