Abstract: A memory access method and device are provided. A memory access method may include: identifying, when an access to a page of a remote memory occurs, a type of the access; allocating a sparse buffer when the access is a sparse write; storing data for the sparse write in the sparse buffer; storing an address for the sparse write as a key and the sparse buffer as a value in a buffer table; and updating an instruction pointer to point to a next instruction.

Abstract: An apparatus for memory integrated management in a cluster system including a plurality of physical nodes connected to each other by a network determines one of the plurality of physical nodes as a node to place a new virtual machine, allocates the first type of memory allocated to the one physical node to the new virtual machine as much as the memory capacity required by the new virtual machine, and distributes the second type of memory to a plurality of virtual machines running on the plurality of physical nodes by integrating and managing the second type of memory allocated to each of the plurality of physical nodes. In this case, the access speed of the second type of memory is faster than that of the first type of memory.
