1. A memory access method performed by an optical interleaver included in a server, comprising:
receiving a request message from a requester processing engine included in the server;
setting receiving buffers corresponding to different wavelengths corresponding to a number of external memory/storage devices connected to the server;
multiplexing the same request message at the different wavelengths according to a wavelength division multiplexing (WDM) scheme; and
transmitting the multiplexed request messages to the respective external memory/storage devices,
wherein an address of a virtual memory managed by the server is separated and stored according to an interleaving scheme by a responder included in each of the external memory/storage devices.
