The tracking mechanism may allow users to track identifying information of other users who perform actions on the shared resource. This sensing and latching scheme allows for the fast execution Read, Write, Write-back, and Refresh operation. For example, a distance between the write word line and the tunneling magneto-resistance element is smaller than a distance between the bit line and the tunneling magneto-resistance element.
