Abstract: A storage device includes a solid state drive (SSD), a field programmable gate array (FPGA), a power sensor and a global controller. The SSD stores data and receives power through a power rail connected to a host device. The FPGA processes data read from the SSD or data to be stored in the SSD and receives power through the power rail. The power sensor is connected to the power rail and generates a measured power value corresponding to a total power consumed by the SSD and the FPGA by measuring the total power. The global controller determines one of the SSD and the FPGA as a priority component operating with a fixed performance and determines the other of the SSD and the FPGA as a non-priority component operating with a variable performance in a priority mode based on power control information provided from the host device.

Abstract: A storage device, including a nonvolatile memory device comprising a plurality of memory cells; and a controller configured to: allocate a plurality of zones to a storage space of the nonvolatile memory device based on a request received from an external host device, fixedly and sequentially manage logical addresses of data written in the plurality of zones, generate a first page map table corresponding to a first zone based on performing the write operation on the first zone, the first page map table comprising a logical address and a physical address of the first zone, based on the first zone being full, activate a read service, which is based on the zone map table, and based on the read service being activated, process read requests for the first zone from the external host device using the zone map table.

Abstract: A storage device, including a nonvolatile memory device including a plurality of memory cells forming a user area and a reserved area; and a controller configured to perform a write operation on at least one write unit included in the plurality of memory cells, and to perform an erase operation on at least one erase unit included in the plurality of memory cells, wherein the controller includes an internal buffer, wherein the controller is configured to: perform a backup operation by writing first data stored in the internal buffer in a backup erase unit included in the reserved area, and after performing the backup operation adjust a buffering unit of the internal buffer to correspond to a cell type of the backup erase unit.
