STORAGE CELL SYSTEM IN WHICH AN ELECTRIC RESISTANCE OF A STORAGE ELEMENT REPRESENTS AN INFORMATION UNIT AND CAN BE INFLUENCED BY A MAGNETIC FIELD, AND METHOD FOR PRODUCING SAME

摘要

According to the invention a storage cell comprises a storage element whose electric resistance represents an information unit and can be influenced by a magnetic field as well as a transistor which when the information is read out allows for the corresponding storage cell to be selected from among the storage cells. To write the information unit the invention provides for a write line (SLa) and a bit line (Ba) which intersect in the area of the storage element and are able to generate the magnetic field. The storage element and the transistor can be connected in series. The storage cell can be mounted between the bit line (Ba) and a shared voltage supply connection for the storage cells. The storage cell can be mounted between the bit line (Ba) and the write line (SLa) and the write line (SLa) can coincide with a gate line (GLa) which controls the transistor. The transistor can be configured in a planar or vertical manner. The storage element and the transistor can be positioned next to or on top of each other.
