Information recording device and method of manufacturing the same

An information recording device comprising:

• first and second electrodes;
• a variable resistance layer between the first and second electrodes;
• and
• a control circuit which controls the variable resistance layer to n (n is a natural number except 1) kinds of resistance,
• wherein the variable resistance layer comprises a material filled between the first and second electrodes, and particles arranged in a first direction from the first electrode to the second electrode in the material, and each of the particles has a resistance lower than that of the material,
• wherein a resistance of the variable resistance layer is decided by a short between the first electrode and at least one of the particles via a filament made of Ag and extending from the first electrode into the variable resistance layer under control of the control circuit, the first electrode includes Ag, and the particles includes one of Co, Pb, Ge, Mo and W.
