Abstract
The following description relates to a virtual memory system, and a virtual memory system based on a storage device supporting massive storage input/output with improved system feature by corresponding a page size, i.e., an elementary unit of a virtual memory with a read/write unit of a storage device that supports massive storage input/output (I/O). The virtual memory system based on a storage device supporting massive input/output based on an NAND flash memory includes a main memory; a storage device configured to read/write data with a certain page unit; a virtual memory that corresponds with the main memory and read/write data that is determined with a page unit size different from the storage device; and a controller configured to recognize read/write unit of the storage device and the virtual memory and control the respective units to correspond with each other and, wherein the controller is configured to correspond between the data read/write unit of the virtual memory and a data unit of the storage device. The virtual memory performs read/write operation of data based on a page unit of the storage device that is corresponding by the controller. The virtual memory read/write a data based on a multiple a page unit of the storage device.
