Title: Integrated circuit memory having a fuse detect circuit and method therefor
Inventor: STARNES GLENN E
IPC: G11C29/02
Filed: 2000-02-11
Granted: 2001-10-11
Abstract: Fuses and detect circuits (124) in an integrated circuit memory (100) include a copper fuse (208) and a fuse state detect stage (202) for detecting the open circuit state or the closed circuit state of the fuse (208). The fuse detect circuit (124) provides an output signal corresponding to the state of the fuse and during detecting, limits a voltage drop across the fuse to an absolute value independent of a power supply voltage applied to the integrated circuit memory. The fuse detect circuit (124) operates at power up of the integrated circuit memory (100) and is disabled after the state of the fuse is detected and latched, and the power supply is sufficient for reliable operation of the integrated circuit memory (100). By limiting the voltage drop across a blown copper fuse (208), a potential electro-migration problem is reduced.

Title: Phase detector for a phase-locked loop
Inventor: WURSTHORN EDGAR
IPC: H03L7/091
Filed: 2000-08-04
Granted: 2002-02-21
Abstract: The invention proposes a phase detector (90) for a phase-locked loop. In this context, it relates to an improvement in the phase detector (90) which can be used in a digital PLL circuit. The invention consists in a sampled and digitized data signal being supplied to the phase detector (90) as an input signal. This data signal is delayed by a sampling clock signal in a delay stage (52). The delayed data signal and the undelayed data signal are then supplied to a subtraction stage (53). The difference between the two input values is formed in this subtraction stage. The differential value determined is then analysed in a processing stage (54) and one of a plurality of possible values is assigned to it. This is done on the basis of the value range in which the differential value is situated. The assigned value is then passed on as an output value to a filter/control stage (60), at whose output a phase error can then be tapped off. The solution described can be integrated very easily on a chip and affords a very advantageous response for the PLL control.

Filed: 2000-09-28
Granted: 2002-11-11
Abstract: A device supplies an output value Y in response to an input value X in accordance with a given function F. The function F can be, for example, a gamma correction function for a video signal. The device operates as follows. An input section (INP) derives a table input value (XT) and an interpolator input value (XI) from the input value (X). A table (TBL) supplies a table value (YT) in response to the table input value (XT). An interpolator (INT) supplies an interpolation value (YI) in response to the interpolator input value (YI). An output section (OUT) combines the table value (YT) and the interpolation value (YI) so as to obtain the output value (Y). The input section (INP) comprises an interval detector (DET) which defines a plurality of input value intervals (I1, I2). This detector (DET) supplies an interval indication (IND) which indicates the interval (I1) in which the input value (X) lies. The input section (INP) further comprises an input value former (IVC) for forming the table input value (XT) and the interpolator input value (XI) in dependence on the interval indication (IND). The table input value (XT) and the interpolator input value (XI) are determined, respectively, by a more significant part (MSP) of the input value and the complementary less significant part (LSP) of variable magnitudes in accordance with the interval indication (IND). By means of such a device a satisfactory accuracy of the output value can be obtained while the table is of a moderate size.

Abstract: There is provided a network movie system, which is constructed as a website designed and manufactured particularly based on Internet characteristics for enabling the user to understand all information related to movies by a multi-media interactive manner and select the desired movie segment based on his/her connecting time. By employing the concept of layer and non-linear video editing, the movie picture is cut into different layers (such as front view, middle view, and background) based on the view-finding distance. Each layer can be individually modified and edited, thereby greatly reducing the modifying time and making the editing more flexible. With the high-quality movie resolution of 720*486 pixel, it is able to exhibit true dynamic image by applying special image processing efficacy and 2D computer animation. Moreover, 2D vector animation is applied at a proper time in the movie to simulate a dynamic effect, thereby greatly reducing the amount of data in a file and increasing the transmission speed.
