Systems and apparatus are provided for power management of non-volatile storage (NVM) systems. A storage controller includes a command queue and a processor. The processor is configured to, in response to a data transfer rate from a host falling below a predetermined threshold and the command queue containing no command, enter a pseudo-idle power state by turning off input and output (IO) drivers of a memory interface coupling the storage controller and a non-volatile memory device and keeping on an internal memory of the storage controller.

System and method for power management in solid state storage systems

Systems, apparatus and methods are provided for power management of non-volatile storage (NVM) systems. A non-volatile storage system may include a first interface to be coupled to a host, a NVM device, a storage controller including a command queue and a processor, and a second interface coupling the storage controller and the NVM device. The processor may be configured to handle data transfer requests from the host in an active power state, monitor the command queue and a data transfer rate on the first interface, determine that the data transfer rate falls below a predetermined threshold and the command queue is empty, enter a pseudo-idle power state, determine that there is a new command from the host, and exit the pseudo-idle power state and enter the active power state.
