  • High performance embedded semiconductor memory devices with multiple dimension first-level bit lines
    Patent number: 5825704
    Abstract: A dynamic random access memory solves long-existing tight pitch layout problems using a multiple-dimensional bit line structure. Improvement in decoder design further reduces total area of this memory. A novel memory access procedure provides the capability to make internal memory refresh completely invisible to external users. By use of such memory architecture, higher performance DRAM can be realized without degrading memory density. The requirements for system support are also simplified significantly.
    Type: Grant

  • Optical location tracking devices
    Patent number: 5393970
    Abstract: A practical location tracking device provides cost-efficient methods for inputting three-dimensional location information. This device comprises light sources and light receiving elements. Each light receiving element comprises two or more closely spaced planar light detectors with their light receiving surfaces facing different spatial directions. Three dimensional location is determined by comparing the relative light intensities detected by those light detectors.
