Abstract
A data storing apparatus in which a magnetic storing means includes magnetic memory cells for memorizing data of a first value or a second value. Input data is written to the memory cells separately or simultaneously by electromagnetic induction. One or more magnetic memory cells are selected, with respect to which the data is to be read or written. Each magnetic memory cell has a ferromagnetic body holding the data of the first value or the second value in accordance with direction of magnetization or magnetizing force thereof. The current control means performs the reading or writing of the data with respect to the selected magnetic cells. The current control means comprises semiconductor devices and controls current therethrough in both directions.
Claims19
A data storing apparatus including integrated magnetic memory cells and semiconductor devices, comprising:
- magnetic storing means having said magnetic memory cells, each of which memorizes data of a first value or a second value;
- data input means through which said data is input to said apparatus;
- data writing means for writing said data which is input from said data input means at said memory cells separately or simultaneously in accordance with electromagnetic induction;
- selection means for selecting one or more magnetic memory cells from which said data is to be read, or which said data is to be written;
- and
- data output means for outputting said data which is read from a data reading means from said apparatus;
- each of said magnetic memory cells having a ferromagnetic body holding said data of the first value or the second value according to direction of magnetization or magnetizing strength thereof;
- current control means for performing the reading of said data from said selected magnetic cell or cells and the writing of said data into said selected magnetic cell or cells, said current control means comprising said semiconductor devices and controlling current therethrough in both directions.
