Device Sleep Partitioning and Keys

摘要

A data storage device includes a device sleep state pin and device sleep state logic to allow the data storage device to store security keys and necessary device sleep state logic together in a volatile logical data storage element. The volatile logical data storage element may be on-chip or off-chip. Device sleep state logic parameters for powering down PHYs while in a device sleep state determine the power characteristics of the device sleep state.
