A new read scheme is provided for an MRAM bit having a reference layer
(fixed) and a storage layer (free) sandwiching a nonmagnetic spacer
layer. The reference layer has a magnetization direction that is tilted
with respect to an easy axis of the storage layer. By applying a magnetic
field to the bit at least partially orthogonal to the easy axis, the
magnetization direction of the storage layer can be partially rotated or
canted without switching the logical state of the MRAM bit. The
resistivity of the bit is measured (calculated based on a voltage/current
relationship) in two ways: (i) with the magnetization direction of the
storage layer partially rotated in a first direction and (ii) with the
magnetization direction of the storage layer in its bi-stable orientation
parallel to the easy axis. Those measures can then be used to compare and
determine the logical state of the storage layer.
