Abstract:
A method of fabricating a ferroelectric or layered superlattice DRAM compatible with conventional silicon CMOS technology. A MOSFET is formed on a silicon substrate. A thick layer of BPSG followed by a thin SOG layer overlies the MOSFET. A capacitor is formed by depositing a layer of platinum, annealing, depositing an intermediate layer comprising a ferroelectric or layered superlattice material, annealing, depositing a second layer of platinum, then patterning the capacitor. Another SOG layer is deposited, contact holes to the MOSFET and capacitor are partially opened, the SOG is annealed, the contact holes are completely opened, and a Pt/Ti/PtSi wiring layer is deposited.

Abstract:
An optical disc for a sample servo type optical disc system. Servo areas disposed periodically on each of tracks of the optical disc are sequentially offset relative to those on the adjacent tracks as viewed in the radial direction by a predetermined distance. An apparatus used for signal read-out from the optical disc comprises a circuit for detecting a servo signal originating in servo pits from a detection signal output from a photodetector, a circuit for generating a clock signal synchronized with the servo signal, a counter for outputting a count value representative of the counted clocks at the timing of the servo signal, and a circuit for generating a light spot velocity signal from the count value.

Abstract:
A method for selecting a picture prediction mode from a candidate pool of picture prediction modes for video compression takes advantage of similarity in implementation between SKIP and DIRECT modes and one other inter-picture prediction modes, namely, the 16×16 partition mode. The SKIP/DIRECT modes are considered if and only if the final prediction information of the 16×16 partition mode, including motion vector, reference picture index, and prediction direction, is the same as that of the respective SKIP and/or DIRECT modes. The same motion prediction, reference picture index and prediction direction are used for the 16×16 partition mode and the SKIP/DIRECT modes, and therefore, the same interpolation scheme can be used for both SKIP/DIRECT and 16×16 partition modes.
Abstract:
The approach of the present invention is to take advantage of similarity in implementation between SKIP and DIRECT modes and one other inter-picture prediction modes, namely, the 16×16 partition mode. The SKIP/DIRECT modes are classified into two groups, one involving inter-picture prediction in one temporal direction in which prediction is chosen from either past or future recon pictures, and the other involving prediction in two temporal directions in which prediction is constructed as a superposition of both past and future recon pictures. The first group requires interpolation for only one direction, whereas the latter requires interpolation for both directions, thus requiring roughly twice as much data processing power than the first group. The 16×16 partition mode also allows both prediction schemes, either past or future, or a superposition of past and future. The SKIP/DIRECT and 16×16 partition modes all apply the same motion vector on the entire block unit.Methods of the present invention consider the SKIP/DIRECT modes if and only if the final prediction information of the 16×16 partition mode, including motion vector, reference picture index, and prediction direction, is the same as that of the respective SKIP and/or DIRECT modes. The point here is that the same motion prediction, reference picture index and prediction direction are used for the 16×16 partition mode and the SKIP/DIRECT modes, and therefore, the same interpolation scheme can be used for both SKIP/DIRECT and 16×16 partition modes, thus saving computational cost as well as implementation cost.
