Latest Patents

Ido holds a patent for a "Large-capacity magnetic memory using carbon nano-tube." This invention describes a high-capacity magnetic memory capable of writing and reading a magnetic record in/from a magnetic recording film according to a perpendicular magnetic recording system. The system operates at high speed in a purely-electrically random access manner. The magnetic memory features a writing-magnetic-field generating means and a writing word line disposed relative to a perpendicular magnetic recording film. Additionally, a reading/writing bit-line conductor, a magnetoresistive-effect element, and a reading word lead conductor are laminated in order on a probe substrate opposed to the perpendicular magnetic recording film. A magnetic probe composed of a carbon nanotube containing a soft magnetic material is positioned relative to the magnetoresistive-effect element in a standing manner and is electrically connected to the reading/writing bit-line conductor. During the writing operation, a micro-discharge is generated in a micro-gap between the edge of the magnetic probe and the magnetic recording film under a writing magnetic field. This allows a writing current to flow through the micro-gap, heating a micro-region of the magnetic recording film to its Curie point, thereby magnetizing it in the direction of the recording magnetic field to form a magnetic record. During the reading operation, the magnetic record is read out through the magnetic probe in accordance with a current variation in the magnetoresistive-effect element.
