The invention relates to a magnetic memory with write inhibit selection
and the writing method for same. Each memory element of the invention
comprises a magnetic tunnel junction (70) consisting of: a magnetic
layer, known as the trapped layer (71), having hard magnetisation; a
magnetic layer, known as the free layer (73), the magnetisation of which
may be reversed; and an insulating layer (72) which is disposed between
the free layer (73) and the trapped layer (71) and which is in contact
with both of said layers. The free layer (73) is made from an amorphous
or nanocrystalline alloy based on rare earth and a transition metal, the
magnetic order of said alloy being of the ferrimagnetic type. The
selected operating temperature of the inventive memory is close to the
compensation temperature of the alloy.
