Abstract: 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.

Abstract: A storage device includes a first memory, a second memory, and a memory controller. The memory controller may include a first controller configured to access the first memory according to a request of an external host device, and a second memory controller configured to access the second memory according to the request of the external host device. The first memory and first memory controller may be configured so that the first memory operates according to a first configuration type, and the second memory and second memory controller may be configured so that the second memory operates according to a second configuration type different from the first configuration type. The memory controller is configured to receive the request from the external host device and based on the request, to store write data to the first memory, and store metadata about the write data to the second memory.
