A method of operating a computing device includes a storage device receiving a request to execute an application instance, and executing the application instance at the storage device in response to the received request by the storage device. The application instance includes a plurality of storage instances connected with one another, and at least one of the plurality of storage instances is connected to a host device.

Operating methods of computing devices comprising storage devices including nonvolatile memory devices, buffer memories and controllers

A method of searching for data in a storage device is provided. The method includes determining, by the storage device, selectivity about read units of the storage device based on a query, with respect to each table stored in the storage device and searching for the data in the storage device based on the selectivity about the read units.

Method for searching for data in storage device

A server device includes a plurality of interface circuits configured to connect with a network, and perform format conversion between network packets and data chunks, the network packets being packets communicated with the network, the data chunks complying with an internal format; a plurality of memory modules operating independently of each other; and a switch circuit connected between the plurality of interface circuits and the plurality of memory modules, the switch circuit being configured to select at least one memory module from among the plurality of memory modules based on an attribute of a first data chunk transmitted from the plurality of interface circuits and, send the first data chunk to the selected memory module, wherein the selected at least one memory module is configured to, decode the first data chunk, and perform a read or write operation associated with the first data chunk based on the decoding result.

Server device including interface circuits, memory modules and switch circuit connecting interface circuits and memory modules

A method of managing a semiconductor memory is provided which includes sampling a row address from an access stream on a memory cell array according to a sampling period; determining whether the sampled row address is an address corresponding to a target row which is most frequently accessed, based on probability information; and executing a refresh operation on rows adjacent to the target row.

Method of detecting most frequently accessed address of semiconductor memory based on probability information

A memory system includes a memory controller configured to replace a memory block including a failed memory cell with a unit cache block of a cache memory in response to detection of the failed memory cell in the memory block. The unit cache block is smaller than a minimum size of a memory cell array capable of being blocked by an operating system, and the unit cache block has substantially the same storage capacity as the memory block.
