  • Patent number: 11784149
    Abstract: Embodiments herein describe a multiple die system that includes an interposer that connects a first die to a second die. Each die has a bump interface structure that is connected to the other structure using traces in the interposer. However, the bump interface structures may have different orientations relative to each other, or one of the interface structures defines fewer signals than the other. Directly connecting the corresponding signals defined by the structures to each other may be impossible to do in the interposer, or make the interposer too costly. Instead, the embodiments here simplify routing in the interposer by connecting the signals in the bump interface structures in a way that simplifies the routing but jumbles the signals. The jumbled signals can then be corrected using reordering circuitry in the dies (e.g., in the link layer and physical layer).

  • Patent number: 11763870
    Abstract: Apparatuses, systems, and methods for ferroelectric memory (FeRAM) cell operation. An FeRAM cell may have different charge regions it can operate across. Some regions, such as dielectric regions, may operate faster, but with reduced signal on a coupled digit line. To improve the performance while maintaining increased speed, two digit lines may be coupled to the same sense amplifier, so that the FeRAM cells coupled to both digit lines contribute signal to the sense amplifier. For example a first digit line in a first deck of the memory and a second digit line in a second deck of the memory may both be coupled to the sense amplifier. In some embodiments, additional digit lines may be used as shields (e.g., by coupling the shield digit lines to a ground voltage) to further improve the signal-to-noise ratio.
