Appeal No. 2004-2166
Application No. 09/492,557
THE INVENTION
The appellant claims a magnetic memory having a keeper
structure for preventing disruptions to magnetization in a sense
layer. Claim 34 is illustrative:
A magnetic memory, comprising:
magnetic memory cell including a sense layer having an
easy axis;
keeper structure for applying magnetic fields using
exchange coupling to a pair of edge regions of the sense
layer that force magnetizations in the edge regions to have
a substantially similar direction which is substantially
perpendicular to the easy axis of the sense layer, the
keeper structure having a proximity to the sense layer which
provides a flux closure path between the edge regions.
