Patent number: 7280410Abstract: A DRAM device includes a mode register that is programmed to select one of two modes for operating data bus terminals in the device. A timing circuit generates timing signals in synchronism with the clock signal that correspond to the selected mode. The timing signals are combined with read data signals to generate corresponding timed read data signals. These timed data signals and termination signals from the timing circuit are applied to pull-up and pull-down circuitry, which drive respective pull-up and pull-down transistors coupled to the data bus terminals. The transistors drive the data bus terminals to either a first or a second voltage if the first mode of operation is selected and to either a third or a fourth voltage if the second mode of operation is selected. Additionally, the pull-up and pull-down transistors bias the data bus terminals to respective voltages corresponding to the selected operating mode.Type: GrantFiled: October 3, 2006Date of Patent: October 9, 2007Assignee: Micron Technology, Inc.Inventors: Jeffrey W.

Publication number: 20070097781Abstract: A calibration circuit for calibrating the input data path of a digital circuit is disclosed. A simple string of a repeating data pattern such as, e.g., “1100,” is sent on the data path. The digital circuit captures the data using a clock signal, examines the data signal for the predetermined pattern and adjusts a delay applied to the data signal until the predetermined pattern is recognized. Then the delay is further adjusted until the predetermined pattern is no longer recognized indicating that an edge of the eye of the data is near a clocking edge of the clocking signal. The delay applied to the data signal is then further adjusted by a predetermined amount to position the clock edge near the center of the data eye.Type: ApplicationFiled: December 19, 2006Publication date: May 3, 2007Inventors: Wen Li, Christopher Morzano

Publication number: 20060250163Abstract: The present invention provides a clock signal input circuit that is able to provide inverse internal clock signals generated by the same input buffer as the address and data signals which exhibit reduced skew. When a skewed external noninverse clock signal and a corresponding external inverse clock signal are passed through respective reference voltage input buffers there is no reduction in skew between the two internal signals. In a preferred embodiment, the invention provides back to back inverters connected to both lines carrying the noninverted and inverted internal clock signals. The slower internal clock signal has an extra inverter driving it when it switches states and the faster internal clock signal has an extra inverter fighting it when it switches states. The skew of the two signals is reduced, allowing for faster operation of the integrated circuit and a reduction in misread data signals.Type: ApplicationFiled: July 11, 2006Publication date: November 9, 2006Inventor: Christopher Morzano
