20130299977 | RAMP-STACK CHIP PACKAGE WITH VARIABLE CHIP SPACING - A chip package includes a stack of semiconductor dies or chips that are offset from each other, thereby defining a terrace with exposed pads. Moreover, surfaces of each of the semiconductor dies in the stepped terrace include two rows of first pads approximately parallel to edges of the semiconductor dies. Furthermore, the chip package includes a high-bandwidth ramp component, which is positioned approximately parallel to the terrace, and which has a surface that includes second pads arranged in at least two rows of second pads for each of the semiconductor dies. The second pads are electrically and mechanically coupled to the exposed first pads by connectors. Consequently, the electrical contacts in the chip package may have a conductive, a capacitive or, in general, a complex impedance. Furthermore, the chips and/or the ramp component may be positioned relative to each other using a ball-and-pit alignment technique. | 11-14-2013 |
20140052713 | HARDWARE IMPLEMENTATION OF THE AGGREGATION/GROUP BY OPERATION: FILTER METHOD - Techniques are described for performing grouping and aggregation operations. In an embodiment, a request is received to aggregate data grouped by a first column. In response to receiving the request, values are loaded from the first column into an input cache. The values include values, from the first column, from a set of rows. A filter unit is programmed with logic to perform a comparison between a particular value, from the first column of a first row, and values in the first column of a plurality of rows, of the set of rows. Based on the comparison, a predicate result is generated that identifies rows, within the plurality of rows, that have a valued in the first column that matches the particular value. An aggregate value for a second column is generated by aggregating values, from the second column, of each of the rows identified by the predicate result. | 02-20-2014 |
20140052743 | HARDWARE IMPLEMENTATION OF THE FILTER/PROJECT OPERATIONS - Techniques are described for performing filter and project operations. In an embodiment, a set of predicates that specify criteria for filtering results to a query is received. Based on a particular predicate of the set of predicates, a predicate result for at least one portion of a particular column is generated. The predicate result identifies rows within the first column that satisfy the particular predicate. Rows are selected and returned as results to the query based at least in part on the predicate result. In an embodiment, the predicate result is a bitvector where each bit of the bitvector corresponds to a particular row within the particular column and identify whether the particular row satisfies the particular predicate. | 02-20-2014 |
20140099892 | OFFSET CANCELLATION FOR DC ISOLATED NODES - Offset voltages developed on floating nodes on inputs to high-performance amplifiers that are DC isolated from the data signals input to amplifiers are cancelled by connecting a highly resistive element between the input node and a predetermined potential, particularly useful in proximity communication systems in which two chips are connected through capacitive or inductive coupling circuits formed jointly in the two chips. The resistive element may be an off MOS transistor connected between the node and a desired bias voltage or a MOS transistor with its gate and drain connected to the potential. Multiple bias voltages may be distributed to all receivers and locally selected by a multiplexer for application to one or two input nodes of the receiver. The receiver output can also serve as a predetermined potential when the resistive element has a long time constant compared to the data rate or the resistive element is non-linear. | 04-10-2014 |
20140185352 | CONFIGURABLE-WIDTH MEMORY CHANNELS FOR STACKED MEMORY STRUCTURES - The disclosed embodiments provide a chip package that facilitates configurable-width memory channels. In this chip package, a semiconductor die is electrically connected to two or more memory chips. More specifically, contacts on each individual memory chip are each directly connected to a distinct set of contacts on the semiconductor die such that the semiconductor die has separate, unique command and address buses to individually address and communicate with each individual memory chip. Individually addressable memory chips that are each accessed via separate command and address buses facilitate a configurable-width memory channel that efficiently supports different data-access granularities. | 07-03-2014 |
20140321803 | HYBRID-INTEGRATED PHOTONIC CHIP PACKAGE WITH AN INTERPOSER - A chip package includes an optical integrated circuit (such as a hybrid integrated circuit) and an integrated circuit that are adjacent to each in the chip package. The integrated circuit includes electrical circuits, such as memory or a processor, and the optical integrated circuit communicates optical signals with very high bandwidth. Moreover, a front surface of the integrated circuit is electrically coupled to a front surface of the optical integrated circuit by a top surface of the interposer, where the top surface faces the front surface of the integrated circuit and the front surface of the optical integrated circuit. Furthermore, the integrated circuit and the optical integrated circuit may be on a same side of the interposer. By integrating the optical integrated circuit and the integrated circuit in close proximity, the chip package may facilitate improved performance compared to chip packages with electrical interconnects. | 10-30-2014 |
20140321804 | HYBRID-INTEGRATED PHOTONIC CHIP PACKAGE WITH AN INTERPOSER - A chip package includes an optical integrated circuit (such as a hybrid integrated circuit) and an integrated circuit that are proximate to each other in the chip package. The integrated circuit includes electrical circuits, such as memory or a processor, and the optical integrated circuit communicates optical signals with very high bandwidth. Moreover, a front surface of the integrated circuit is electrically coupled to a top surface of an interposer, and this top surface is in turn electrically coupled to a front surface of an input/output (I/O) integrated circuit that faces the top surface. Furthermore, the front surface of the I/O integrated circuit is electrically coupled to a top surface of the optical integrated circuit, where the top surface of the optical integrated circuit faces the front surface of the I/O integrated circuit. | 10-30-2014 |
20150071021 | ACCESSING INDEPENDENTLY ADDRESSABLE MEMORY CHIPS - A method of accessing rows and columns stored in a memory system that include memory chips that can be individually addressed and accessed is described. In order to leverage this capability, prior to performing a row-write request on the memory system, a computer system may transform the rows and the columns in a matrix. In particular, in response to receiving a row-write request to write to a row N in the matrix, the computer system rotates the row right by N elements, and writes the row in parallel to address N of the memory chips in the memory system. Similarly, in response to receiving a column-write request to write to column M in the matrix, the computer system rotates the column right by M elements, and writes the column in parallel to the memory chips in the memory system. | 03-12-2015 |
