    摘要: More efficient use of silicon area is achieved by incorporating an electrostatic discharge protective (ESDP) device beneath a pad area of a semiconductor structure. The pad area includes a substrate having a first metal layer above it. A second metal layer is above the first metal layer. The ESDP device resides in the substrate below the first metal layer. A layer of dielectric separates the first and second metal layers. A via within the dielectric layer electrically couples the first and second metal layers. A via connects to the ESDP component. Subsequent metal layers can be arranged between the first and second metal layers. The Ohmic value of the resistance component of the ESDP device can be set during fabrication by fixing a number of individual via components, arranged electrically in parallel, by fixing the cross sectional area of the via components, and/or by fixing the length of the via components.

    摘要: A system and method for manufacturing a semiconductor device including multi-layer bitlines. The location of the bitlines in multiple layers provides for increased spacing and increased width thereby overcoming the limitations of the pitch dictated by the semiconductor fabrication process used.

    摘要: A non-volatile memory device includes an array of non-volatile memory cells. When programming the memory cells, a voltage supply source is used that includes multiple independent charge pumps. The independent charge pumps supply the programming voltage to different ones of bit lines in the array of memory cells. Using multiple charge pumps tends to reduce output voltage fluctuations and thereby reduce power loss.

    摘要: Techniques for programming a non-volatile memory device, such as a Flash memory, include floating source lines of memory cells based on a data pattern that is being programmed to the memory device. The source lines to float are selected such that a distance between drain bit lines and source bit lines of different memory cells in a row is maximized. In this manner, leakage current between these drain bit lines and source bit lines can be decreased.

    摘要: The present invention relates to a flash memory array. The flash memory array includes at least two word lines of gate electrode material. At least one of the word lines is connected through a first metal level to a discharge circuit, while other word line(s) may connect to a discharge circuit through a first and second metal level. The memory array further includes a shorting path between the word lines of the memory array. The shorting path is a high resistance layer of undoped gate electrode material. The resistance value of the gate electrode material is such that the word lines can be used to read, write, or erase without effecting each other, but that during the formation of a first metal level, as charges will build up on a first word line which requires a second metal level to connect to its discharge junction circuit, it will short the first word line to an adjacent second word line that has a connection to its junction circuit on the first metal level.
