Steven Schumann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9595335
    Abstract: A memory device comprises memory cells arranged in rows and columns, and source lines associated with memory sections, each of which includes a plurality of memory cells. Source terminals of transistors included in the memory cells in a first memory section are physically coupled to a first source line that is distinct from other source lines associated with other memory sections on a same row of the memory device as the first memory section. Gate terminals of transistors included in memory cells in a row share a common wordline configured for providing a signal to the gate terminals.
    Type: Grant

  • Publication number: 20070251184
    Abstract: A self-supporting, modular wall unit apparatus. A wall unit according to one embodiment of the invention is prefabricated from reinforced lightweight for transportation to the construction site. The wall unit then is placed in prepared ground, where it is self-supporting. The modular wall unit incorporates an integral footer component, eliminating the need to place a separate footing in advance of wall placement. The wall unit typically has the general cross-sectional shape (along at least a portion of its length) of an inverted “T,” with the footer portion extending laterally from opposite sides of the wall. Alternatively, the wall unit may present a non-planar profile or footprint that zigzags or undulates to depart from a vertical plane, to enhance the wall unit's stability with minimized integral footer.

  • Publication number: 20070014140
    Abstract: A nonvolatile memory apparatus includes a separate controller circuit and memory circuit. The controller circuit is fabricated on a first integrated circuit chip. The controller circuit includes a plurality of charge pump circuits, a system interface logic circuit, a memory control logic circuit, and one or more analog circuits. The memory circuit is fabricated on a second integrated circuit chip and includes a column decoder, a row decoder, a control register, and a data register. A memory-controller interface area includes a first plurality of die bond pads on the first integrated circuit chip and a second plurality of die bond pads on the second integrated circuit chip such that the first and second integrated circuit chips may be die-bonded together. A single controller circuit may interface with a plurality of memory circuits, thus further reducing overall costs as each memory circuit does not require a dedicated controller circuit.

  • Publication number: 20050099857
    Abstract: A decoding system for multi-plane memories routes address information corresponding to distinct memory access operations to the designated planes. The system includes an array of functional registers dedicated to random access read, burst read, program, erase, and erase-suspend program operations. Plane selector blocks for each plane receive the address outputs from all of the registers and plane function select logic controls the routing in accord with memory access commands for specified planes. Simultaneous operations of different type in different planes and nested operations in the same plane are possible.

  • Publication number: 20050081011
    Abstract: An apparatus and method identify a plurality of words to be read, read these selected words during a clock latency period, and then shift these words out synchronously at an end of the latency period. In another aspect of the present invention, the above method of reading a plurality of words during a clock latency period and shifting them out synchronously after the latency period is facilitated by a two tier column decoder. The two-tier column decoder has two decoders. A first-tier decoder decodes a first group of words to be read during the latency period, and a second-tier decoder decodes subsequent words to be shifted out synchronously during a burst period.
