Abstract: Disclosed is a heat insulating material composition including crosslinked polyarylene sulfide and glass fiber. The heat insulating material composition according to an embodiment of the present disclosure can realize excellent insulation performance and has excellent impact resistance and support performance, even when provided in a thin thickness. Accordingly, the heat insulating material composition according to an embodiment of the present disclosure can be applied usefully to electronic products, such as a refrigerator, requiring an adiabatic body.

Abstract: Disclosed are a controller and a storage device for efficient buffer allocation, and a method of operating the storage device. The storage device includes a non-volatile memory including a plurality of non-volatile memory cells, a buffer including a plurality of storage spaces to be allocated for a plurality of commands fetched from a host, and a storage controller connected to the non-volatile memory via a plurality of channels, the storage controller being configured to store status information corresponding to a workload of each of the plurality of channels and to allocate the buffer for the plurality of commands, the allocation being based on the status information.
