Independent multi-plane commands for non-volatile memory devices are described. In one example, a three-dimensional (3D) NAND memory device includes 3D NAND dies, each die including multiple planes of memory cells. The device includes input/output (I/O) circuitry to receive multiple commands from a host, each of the received commands to access one of the planes. The device includes logic (which can be implemented with, for example, an ASIC controller, firmware, or both) to queue the commands in separate queues for each of the planes based on a target plane of each of the commands. The logic issues the commands to their target planes independent of other planes' status, and tracks completion status of the commands independently for each plane.

Independent NAND memory operations by plane

A reduction in Quality of Service (QoS) latency for host read commands in a power limited operation mode in a storage device is provided. A priority level is assigned to a host command using weighted round robin arbitration. Power resources are allocated based on the priority levels assigned to host commands to minimize host read command latency in the power limited operation mode.

Method and apparatus to prioritize read response time in a power-limited storage device

In one embodiment, a command for a storage device may be received, wherein the command comprises a plurality of stages. Power for the plurality of stages of the command may be dynamically allocated, wherein power for a first stage of the command is allocated first, and power for each remaining stage of the command is allocated after a preceding stage is performed.

Power management and monitoring for storage devices

A mechanism is described for facilitating power governance of non-volatile memory devices using a power governing mechanism employed at a computing device according to one embodiment of the invention. A method of embodiments of the invention includes maintaining a credit pool having a plurality of credits to be released to a plurality of memory channels associated with a plurality of non-volatile memory devices. The plurality of credits may be used to provide sufficient power to perform memory operations associated with a computing device. The method may further include receiving a credit request having a petition to obtain one or more credits for a memory channel of the plurality of memory channels to facilitate performance of a memory operation, determining whether the one or more credits are available in the credit pool, and retrieving the one or more credits from the credit pool, if the one or more credits are available in the credit pool. The method may further include releasing the one or more credits to the memory channel. The one or more released credits are used to perform the memory operation.
