    摘要: A data input circuit for use in a semiconductor device, the data input circuit reducing a load difference between a fetch signal and a plurality of groups of data. The data input circuit includes first through Nth latching units for latching each one of N groups of data in response to a reference clock, respectively (N is a natural number greater than 2), and a bus for transmitting the reference clock and the N groups of data to the first through Nth latching units. Each of the first through Nth latching units includes a clock buffer for buffering the reference clock; a data buffer for buffering a corresponding group of data of the N groups of data; N−1 dummy elements for respectively receiving each one of the N groups of data, except for the group of data input to the data buffer; and latches for latching data output from the data buffer in synchronization with a signal output from the clock buffer. Use of the data input circuit makes a load on a reference clock the same or substantially the same as that on each group of data. Therefore, a load difference between the reference clock and each group of data is reduced to reduce a skew therebetween.

    摘要: An embodiment of the invention comprises a digital phase detector with substantially zero phase offset. The digital phase detector receives a clock signal and a reference clock signal and provides a phase indicator signal to identify whether the clock signal leads or lags the reference clock signal. An embodiment of the invention comprises a method that adds substantially zero phase offset in processing an input clock signal and a delayed clock signal to generate a control signal. The control signal is processed in a variable delay line to generate the delayed clock signal. In an embodiment, a first processor comprises a delay locked loop having a digital phase detector, the digital phase detector comprising a first differential sense amplifier cross-coupled to a second differential sense amplifier, the digital phase detector receiving a clock signal and generating one or more delayed clock signals, a control signal, and a gated data signal.

    摘要: A stacked 3D integrated circuit structure is manufactured with a common image design for dies which allows diced master dies to cut from the common wafer and diced slave dies cut to be cut from a wafer which has the common image design. In an embodiment is stacked to form a wafer-to-wafer 3D stack before dicing. Master and slave elements which are used for only one kind of separated individual integrated circuit dies which are located along die edges and at die centers before dicing separation of individual integrated circuit chips. A master wafer is shifted ½ way across a die to make cutting along a kerf line effective to provide both master and slave dies. Multiple slaves can be stacked and coupled to a master die which acts as a bus master when attached to a bus to which only the master die is directly connected. The use of a common wafer design minimizes cost of manufacture of chips destined to be stacked as 3D integrated circuits.
