Abstract: A scan test methodology is presented. In one embodiment of the present invention, a scan test methodology is implemented which generates a test pattern set. A linear-time analysis is then performed on the test pattern set. As a result a new test pattern set is generated. Comparisons are made between the original test pattern set and the new test pattern set to analyze any difference in faults detected by the original test pattern set and the new test pattern set. If there are any differences in faults, test pattern generation is performed using the new test pattern set and the original test pattern set is used to augment the new test pattern set.

Abstract: This disclosure provides a computer system with operating system permitting dynamic reallocation of main memory during operation. In a particular embodiment the computer system with operating system are used in connection with non-volatile main memory stores (NMS) such as MRAM. As the NMS is a component of main memory attached directly to the memory bus, the NMS functions at substantially the same speed as traditional volatile memory stores. Reallocation of main memory and use of applications or programs stored on the inserted NMS occurs at speeds orders of magnitude greater than traditional secondary memory devices.

Abstract: 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.
