Abstract: In a non-volatile memory system, physically separate power rails are provided from a host system to a NVM device for independently power cycling a controller and memory array in the NVM device. The controller of the NVM device can send a power cycle request signal to the host system over a host channel, or updates a status register in the NVM device. The host system receives and decodes the power cycle request signal, or reads the status register, and performs the power cycle request, which can include power cycling the controller or the memory array in the NVM device, or both. The power cycle request can be based on a power state of the non-volatile memory system, which can be managed by the controller or the host system, or both.
