Abstract
A micro magnetic core memory having a magnetic core, which serves as a storage medium, a coil, which is located in close vicinity to the magnetic core and magnetizes the magnetic core, and a sensor, which is located in close vicinity to the magnetic core and detects polarity of magnetization of the magnetic core. The micro magnetic core memory has the effects in that the inputting and the outputting of information can be carried out quickly, in that a high degree of integration can be achieved easily and a storage device having a large capacity can be produced at a low cost, and in that the stored information is not lost when the supply of electric power is turned off.
Claims12
A micro magnetic core memory, comprising:
- i) a magnetic core, which serves as a storage medium, having a top surface, a bottom surface and a connecting surface extending between said top surface and said bottom surface,
- ii) a coil wound around a periphery of said connecting surface of said magnetic core, said coil being operable to magnetize said magnetic core, and
- iii) a magnetic polarity sensor located in opposition to one of said top surface and said bottom surface of said magnetic core and being operable to detect polarity of magnetization of said magnetic core.
A method of inputting and outputting information, comprising the steps of:
- i) employing a magnetic core, which is a magnetic material having a top surface, a bottom surface and a connecting surface extending between said top surface and said bottom surface, as a storage medium,
- ii) winding at least one coil around a periphery of said connecting surface of said magnetic core, said coil serving to magnetize said magnetic core,
- iii) magnetizing said magnetic core by said coil, information being thereby written into said magnetic core,
- iv) locating at least one sensor in opposition to one of said top surface and said bottom surface of said magnetic core, said sensor serving to detect polarity of magnetization of said magnetic core, and
- v) detecting the polarity of magnetization of said magnetic core by said sensor, the written information being thereby read from said magnetic core.
