  • Publication number: 20130044537
    Abstract: There is provided a magnetic memory with using a magnetoresistive effect element of a spin-injection magnetization reversal type, in which a multi-value operation is possible and whose manufacturing and operation are simple. A preferred aim of this is solved by providing two or more magnetoresistive effect elements which are electrically connected in series to each other and by selecting one of the series-connected elements depending on a direction of a current carried in the series-connected elements, a magnitude thereof, and an order of the current thereof for performing the writing operation. For example, it is solved by differentiating plane area sizes of the respective magnetoresistive effect elements which have the same film structure from each other so as to differentiate resistance change amounts caused by respective magnetization reversal and threshold current values required for respective magnetization reversal from each other.

  • Publication number: 20130033928
    Abstract: Since a nonvolatile RAM allows random reading and writing operations, an erasing mode is unnecessary. From the system side, however, it is desirable to have the erasing mode because of its nonvolatile characteristic. Moreover, the erasing operation is desirably carried out at high speed with low power consumption. Therefore, memory cell arrays COA and DTA containing a plurality of memory cells MC each having a magnetoresistive element are provided, a series of data is written to the memory cell arrays COA and DTA, and at the time of erasing, an erasing operation is carried out by writing predetermined data only to the memory cell array COA.
