Abstract
A memory system to manage a memory using a virtual memory is provided. The memory system may use an asymmetric memory as a swap storage of a dynamic random access memory (DRAM). The asymmetric memory may access on a byte basis, allowing a process to directly access a page swapped out to the asymmetric memory through direct mapping.
