摘要： An apparatus that provides for non-destructive readback of a ferroelectric material. The apparatus can include a ferroelectric layer with a scannable surface wherein the ferroelectric layer has a compensation charge adjacent the scannable surface. The apparatus also can include an electrode adjacent the scannable surface to sense the compensation charge. A related method is also disclosed.

摘要： Method and apparatus for writing data to a magnetic memory cell, such as a spin-torque transfer random access memory (STRAM) memory cell. In accordance with various embodiments, a write current is applied through a selected magnetic memory cell to initiate magnetic precession of the selected cell to a desired magnetic state. A field assist current is concurrently flowed through an adjacent memory cell to generate a magnetic field that assists in the precession of the selected cell to the desired magnetic state.
