An integrated digitizing tablet with color display is disclosed. The
digitizing tablet portion of the integrated digitizing tablet and display
apparatus includes an array of magnetic random access memory (MRAM) cells
that can be modified by at least one externally-applied magnetic field,
wherein each memory cell has a magnetic bit that changes orientation upon
the application of the externally-applied magnetic field to produce an
electrical signal based on the orientation of the bit when an electric
field is applied across the array. The display portion comprises an array
of color pixel cells, each color pixel cell being selected from more than
one color type and being coupled to one of the MRAM cells. The MRAM cell
is operated to activate the coupled color pixel cell in response to the
electrical signal produced by the MRAM cell. Typically, the color pixel
cells are selected from the colors red, blue, and green in approximately
equal ratios or may be selected from their complementary colors which
would include cyan, magenta, and yellow. Any color scheme may be
implemented and is not limited to merely three colors or be required to be
more than two.
