  • Publication number: 20100002532
    Abstract: The present invention provides a solution to avoid the robustness problems of sub-threshold circuits by switching small parts of circuits to nominal-voltage only when they are being used, and switching them back to sub-threshold levels when the operation finishes. Such “hybrid sub-threshold” approach is capable of supporting ultra-low power operation without the disadvantages of sub-threshold circuits.

  • Patent number: 6829180
    Abstract: High performance memory devices have been realized by applying an Evenly Scaled Multiple Level Architecture (ESMLA) using block select arrangement. A single-bit-line-write mechanism allows us to reduce the number of bit lines by 50% for static memory devices. The resulting memory device can be as fast as registers files while its area is smaller than prior art high-density memory devices. The scaling method of the memory architecture also assures that the speed of the memory devices will scale in the same rate as logic circuits in future IC manufacture technologies.

  • Patent number: 6687148
    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.
