  • Patent number: 11251148
    Abstract: Semiconductor devices are disclosed. According to some embodiments, a semiconductor device may include a memory array area and a peripheral area. The memory array area may include a number of memory cells and a number of array pads configured to receive an input voltage. The peripheral area may include a number of peripheral pads for interfacing with the memory array area. In these or other embodiments, the peripheral area may be arranged adjacent to a first edge of the semiconductor device and the number of array pads may be arranged proximate to a second edge of the semiconductor device. The second edge may be perpendicular to the first edge. The memory array area may also include an array distribution conductor configured to variously electrically connect the number of memory cells to the number of array pads. A semiconductor-device package and system are also disclosed.

  • Patent number: 6770973
    Abstract: A semiconductor apparatus and method for making the semiconductor apparatus are provided. The semiconductor memory device can include functional circuit blocks (100) having a multi-layer wiring structure for providing electrical connections between device elements within functional circuit blocks (100). Multi-layer wiring structure can include a wiring layer (M2) disposed in a M2 wiring layer horizontal track (120) and a M2 wiring layer vertical track (122). M2 wiring layer horizontal track (120) provides electrical connections by using wiring layer (M2) disposed in a horizontal direction and M2 wiring layer vertical track (122) provides electrical connections by using wiring layer (M2) disposed in a vertical direction. A wiring layer (M1) can form electrodes having electrical connections to diffusion regions of the device elements in functional circuit blocks (100). Wiring layer (M1) can have a higher sheet resistance and higher melting point than wiring layer (M2).
