An integrated digitizing tablet and display apparatus is disclosed. The digitizing tablet portion of the apparatus is comprised of an array of magnetic random access memory (MRAM) cells, wherein each MRAM cell is responsive to an externally applied magnetic field. Each memory cell has a magnetic bit that changes orientation upon application of an externally applied magnetic field to produce an electrical signal based on the orientation of the bit when a second electric field is applied across the array. The display is comprised of an array of pixel cells and each pixel cell is coupled to one of the MRAM cells. The MRAM cell activates the pixel cell by the electrical signal produced by the MRAM cell. Thus, what is achieved is an integrated digitizing tablet and display that has digitizing cells that directly control the display cells without the need for additional processors. |
