Patent ID: 7579614

Claim:
A magnetic random access memory comprising: a semiconductor substrate having a first projection projecting from a substrate surface, the first projection having an upper surface, a first side surface and a second side surface opposing each other; a first gate electrode formed on the first side surface of the first projection; a second gate electrode formed on the second side surface of the first projection; a first source diffusion layer formed in the upper surface of the first projection; a first drain diffusion layer formed in the substrate surface at a root on a side of the first side surface of the first projection; a second drain diffusion layer formed in the substrate surface at a root on a side of the second side surface of the first projection; a first word line formed above the semiconductor substrate; a second word line formed above the semiconductor substrate; a first bit line formed above the first word line and the second word line; a first magnetoresistive effect element formed between the first bit line and the first word line, and connected to the first bit line; a second magnetoresistive effect element formed between the first bit line and the second word line, and connected to the first bit line; a first contact which connects the first magnetoresistive effect element and the first drain diffusion layer; and a second contact which connects the second magnetoresistive effect element and the second drain diffusion layer.
