A smart storage device is provided. The smart storage device includes a smart interface connected to a host device. An accelerator circuit is connected to the smart interface through a data bus conforming to a CXL.cache protocol and a CXL.mem protocol. The accelerator circuit is configured to perform acceleration computation in response to a computation command of the host device. A storage controller is connected to the smart interface through a data bus conforming to a CXL.io protocol. The storage controller is configured to control a data access operation for a storage device in response to a data access command of the host device. The accelerator circuit is directly accessible to the storage device through an internal bus connected directly to the storage controller.

Smart storage device using a computer express link (CXL) interface

A data storage device is provided. The data storage device includes: a first function block of a device controller configured to receive user data and perform a first data processing; a first buffer memory connected to the first function block and configured to store user data subjected to the first data processing as first process data; a second function block of the device controller configured to receive a data write command determined based on the first process data; and a non-volatile memory connected to the second function block, and configured to receive and store data stored in the first buffer memory. The user data is provided to the first function block before the data write command is provided to the second function block.

Distributed processing data storage device and system

A storage controller includes a host interface which real-time analyzes a command received from a host, a programmable logic unit which loads an optimal image adaptively selected from a plurality of images in response to at least one of a current operating state of the storage controller and the command, and a processor which performs an operation on a nonvolatile memory device using the programmable logic unit after the optimal image is loaded.

Data storage device and system

A semiconductor system includes a CPU connected to a heterogeneous memory module via a system bus. The heterogeneous memory module includes; a volatile memory module, a nonvolatile memory module, an internal bus separate from the system bus and connecting the volatile memory module and the nonvolatile memory module, and a swap manager configured to control execution of a swap operation transferring target data between the volatile memory module and nonvolatile memory module using the internal bus and without using of the system bus.
