A rendering system and method. The rendering system may perform rendering using a rendering context stored in an internal memory. When a rendering context to be used is not available in the internal memory, the rendering system may load the rendering context to be used from an external memory into the internal memory. When an insufficient amount of storage space is available in the internal memory, storage space may be secured by selectively deleting a rendering context from the internal memory, and a requested rendering context stored in the external memory may be loaded into the internal memory.
