Abstract: A computing system includes a host, a first electronic device including a memory and an accelerator, and a second electronic device including a direct memory access (DMA) engine. Based on a command transmitted from the host through the first electronic device, the DMA engine transmits data and completion information of the command to the first electronic device. The memory includes a data buffer storing the data and a completion queue buffer storing the completion information. The accelerator executes a calculation on the data. The DMA engine transmits the data to the first electronic device and then transmits the completion information to the first electronic device.

Abstract: A memory system which includes a flash memory including a meta block and a data block, and a memory controller including a meta data managing module managing meta data to be stored in the meta block. The meta block includes a plurality of pages. The meta data managing module compares a number of free pages of the plurality of pages with a preset number of free pages, and selects a write target page of the meta data by using one of a consecution meta write operation or a dirty meta write operation, depending on a result of the comparison.
