In recent years, many efforts have been spent on research on emerging technologies applied to memories. Many different devices are present on the market, each of them with its peculiarity but in general, as a rule of thumb, if the storage capacity increases the speed decreases. Furthermore, the standard technology suffers from physical and technological limitations. Novel technologies try to overcome such limitations, Racetrack technology seems to be a good candidate to satisfy at the same time the requirements of speed and storage capacity. Racetrack is essentially a ferromagnetic wire where bits are retained by exploiting the magnetization direction. Bits are accessed and modified only through dedicated ports, thus this requires bit alignment to the access ports by means of shift operations along the ferromagnetic structure.
