  • Variable data width memory systems and methods
    Patent number: 7539076
    Abstract: Systems and methods disclosed herein provide for variable data width memory. For example, in accordance with an embodiment of the present invention, a technique for doubling a width of a memory is disclosed, without having to increase a width of the internal data path or the number of input/output pads.
    Type: Grant

    Inventors: Hemanshu Vernenker, Margaret Tait, Christopher Hume, Nhon Nguyen, Allen White, Tim Swensen, Sam Tsai, Steve Eplett
  • Bitline twisting scheme for multiport memory
    Patent number: 7414913
    Abstract: A multiport memory in one embodiment of the invention includes a memory cell array, where each column in the array has two exterior complementary bitline pairs and zero, one, or more interior complementary bitline pairs. Across each pair of adjacent columns in the array, the adjacent exterior bitline pairs are associated with the same port in the multiport memory. In addition, within each column, the two exterior bitline pairs have the same, non-zero number of crossovers, and, across each pair of adjacent columns, the exterior bitline pairs have different numbers of crossovers. Furthermore, each column has at least one reference signal line located between the two exterior bitline pairs.
