    Abstract: A method for adding an electrical interconnection within a three-dimensional integrated circuit (3-D IC) is disclosed. The method may include creating, within a design file of a 3-D IC that specifies a layout for a first chip of the 3-D IC, design data corresponding to a set of through-silicon via (TSV) reservation areas. The method may also include receiving an engineering change order (ECO) and releasing, in response to the ECO, at least one TSV reservation area for reuse. The method may also include adding, by re-using at least one TSV reservation area, an electrical interconnection within the design file of the first chip of the 3-D IC.

  • Patent number: 9658853
    Abstract: A technique for operating a processor includes storing a first result to a writeback buffer, in response to a first execution unit of the processor attempting to write the first result of a first completed instruction to a register file of the processor at a same processor time as a second execution unit of the processor is attempting to write a second result of a second completed instruction to the register file. The writeback buffer is positioned in a dataflow between the first execution unit and the register file. A buffer full indicator logic is used to detect that the writeback buffer is unavailable. A buffer unavailable signal is transmitted, from the buffer full indicator logic, in response to detecting the writeback buffer is unavailable. In response to receiving the buffer unavailable signal, a buffer retrieving logic writes the first result from the writeback buffer to the register file.

  • Patent number: 9633928
    Abstract: A through-silicon via access device (TSVAD) for establishing an electrical connection to a through-silicon via (TSV) located in a planar stack of semiconductor chips is disclosed. The TSVAD may include a switching circuit, having a conductive pad terminal, a TSV terminal, an input terminal coupled to a sending logic circuit, an output terminal coupled to a receiving logic circuit, and logic devices to, in response to control signals, couple the TSV terminal to the conductive pad terminal, in one configuration, and couple the TSV terminal to another terminal in another configuration. The TSVAD may also include a control circuit to generate control signals to cause an input selection circuit to drive a signal from the sending logic circuit onto the input terminal, and to cause an output selection circuit to drive a logic signal from the output terminal to the receiving logic circuit.

  • Patent number: 9437285
    Abstract: An aspect relates to a memory array that includes at least a first and a second six transistor static random access memory cell, and first and second address decoders. The first address decoder comprises a first latch, the second address decoder a second latch. First and second address data paths provide first and second address data to the at least two address decoders. The first latch is electrically conductive connected to the first data path and the second latch is electrically conductive connected to the second data path. The first latch is further electrically conductive connectable to the second data path via a first multiplexer. The first multiplexer and the at least two latches are configured to be selectively operated in a first write mode for a write access or in a read mode for a read access to the memory array.
