Abstract
Methods and apparatus for managing power in data storage devices implementing non-volatile memory (NVM) sets are provided. One such apparatus includes a NVM including a first NVM set and a second NVM set, first backend logic circuitry configured to manage data storage in the first NVM set, second backend logic circuitry configured to manage data storage in the second NVM set, and power management circuitry configured to initialize the first and second backend logic circuitry to a high power state, detect an idle state for the first NVM set, store operational settings for the first backend logic circuitry, and transition the first backend logic circuitry to a low power state that consumes less power than the high power state. When a new command arrives, the first backend logic circuitry can be returned to the high power state to handle the command.
