  • Publication number: 20050218937
    Abstract: A phase detector generates a first output signal if a feedback clock signal leads a reference clock signal by more than a first time. The phase detector generates a second output signal if the feedback clock signal lags the reference clock signal by more than a second time. If the feedback clock signal either leads the reference clock signal by less than the first time or lags the reference clock signal by less than the second time, neither output signal is generated. The phase detector may be used in a delay-lock loop in which the first and second output signals increase or decrease a delay of the reference clock signal by respective first and second delay increments. In such case, the each of the first and second delay increments should be less than the sum of the first and second times.

  • Patent number: 6922367
    Abstract: A data strobe synchronization circuit includes first and second logic circuits receiving global data strobe pulses and respective enable signal. A control circuit initially applies an enable signal to the first logic circuit so that the first logic circuit generates a first data strobe pulse responsive to each global data strobe pulse. The control circuit receives a write control signal. When the write control signal becomes active, the control circuit terminates the enable signal applied to the first logic circuit and applies an enable signal to the second logic circuit. The second logic circuit then generates a second data strobe pulse responsive to the next global data strobe pulse. The first and second data strobe pulses are used to latch a data signal in respective flip-flops. The data strobe pulses may latch the data signal in pairs of flip-flops on the leading and trailing edges of the data strobe pulses.

  • Publication number: 20050128277
    Abstract: A method of producing and using photo media to print a glossy, photo-quality image. The image is printed onto the back of a coated transparent base. Thereafter, an opaque backing is applied to cover the printed image. The resulting print is viewed from the front, which provides the photo-quality, attractive appearance primarily because of the substantial gloss depth and uniformity attributable to the transparent base. The transparent base and backing protect the ink-receiving coating and make the resulting print very durable. The image is light fast because the ink is sandwiched between the transparent base and the backing, thereby sealing the ink from oxygen. In a preferred embodiment of the present invention, the backing is applied as a liquid using substantially the same mechanism as used for printing the image.

  • Patent number: 6901013
    Abstract: A method of monitoring the characteristics of a delay locked loop (DLL) in a memory device during a test mode is provided. The DLL generates an internal clock signal based on an external clock signal. The external and internal clock signals are normally synchronized. DLL constantly responds to variations in operating condition of the memory device to keep the external and internal clock synchronized. The method involves preventing the DLL from responding to a change in operating condition such as a change in the supply voltage of the memory device during a test mode.

  • Publication number: 20050085066
    Abstract: A method of forming a copper interconnect in an opening within a pattern is described. The copper interconnect has an Rs that is nearly independent of opening width and pattern density. A first copper layer having a concave upper surface and thickness t1 is formed in a via or trench in a dielectric layer by depositing copper and performing a first CMP step. A second copper layer with a thickness t2 where t2?t1 and having a convex lower surface is deposited on the first copper layer by a selective electroplating method. The first and second copper layers are annealed and then a second CMP step planarizes the second copper layer to become coplanar with the dielectric layer. The invention is also a copper interconnect comprised of the aforementioned copper layers where the first copper layer has a grain density (GD1)?GD2 for the second copper layer.
