    摘要: A magnetic memory cell with symmetric switching characteristics includes a sense layer and a reference layer coupled to the sense layer through a barrier layer. The magnetic memory cell further includes an additional reference layer coupled to the sense layer through a spacer layer. The additional reference layer is formed so that a set of demagnetization and coupling fields from the additional reference layer balance a set of demagnetization and coupling fields from the reference layer.

    摘要: Methods and devices for measuring conductivity of ink in a printing system are disclosed. An embodiment of the method is used with a printing system having a developer roller, wherein the ink is formed on the developer roller using electrostatic forces and is used to print on a substrate. A first current charges the developer roller during the printing. The first current is measured and the conductivity of the ink is determined, wherein the conductivity is proportional to the square of the first current.
