A device includes a storage device to receive a first power and transfer data, a computing device to receive a second power and perform computations on the data; a storage power manager to generate a storage power demand value from previous operation of the storage device; a computing power manager to generate a computing power demand value from previous operation of the computing device; and a global power manager to generate a storage target power value indicating a next power limit for the storage device and a computing target power value indicating a next power limit for the computing device, from both of the storage and computing power demand values, wherein the storage power manager provides the first power to the storage device based on the storage target power value, and the computing power manager provides the second power to the computing device based on the computing target power value.

Computation storage device and method of managing power of the same

A storage device includes a nonvolatile memory device and a storage controller. The storage controller includes a multi-protocol host interface circuit that receives a first-type request including a first logical address from an external host and transmits/receives data corresponding to the first-type request with the external host by a block unit. Additionally, the multi-protocol host interface circuit receives a second-type request including a first physical address from the external host and transmits/receives data corresponding to the second-type request with the external host by a unit smaller than the block unit. A mapping cache manager manages an address translation table cache, sends an address translation request including the first physical address to the external host, and receives a response including mapping information corresponding to the first physical address from the external host.
