A bistable resistance random access memory comprises a plurality of
programmable resistance random access memory cells where each
programmable resistance random access memory cell includes multiple
memory members for performing multiple bits for each memory cell. The
bistable RRAM includes a first resistance random access member connected
to a second resistance random access member through interconnect metal
liners and metal oxide strips. The first resistance random access member
has a first resistance value Ra, which is determined from the thickness
of the first resistance random access member based on the deposition of
the first resistance random access member. The second resistance random
access member has a second resistance value Rb, which is determined from
the thickness of the second resistance random access member based on the
deposition of the second resistance random access member.
