  • Patent number: 7977218
    Abstract: Novel fabrication methods implement the use of dummy tiles to avoid the effects of in-line charging, ESD events, and such charge effects in the formation of a memory device region region. One method involves forming at least a portion of a memory core array upon a semiconductor substrate that involves forming STI structures in the substrate substantially surrounding a memory device region region within the array. An oxide layer is formed over the substrate in the memory device region region and over the STI's, wherein an inner section of the oxide layer formed over the memory device region region is thicker than an outer section of the oxide layer formed over the STI's. A first polysilicon layer is then formed over the inner and outer sections comprising one or more dummy tiles formed over one or more outer sections and electrically connected to at least one inner section.

  • Patent number: 7969901
    Abstract: In a buffer (10) to compensate for runtime fluctuations of data packets (1) transmitted over a transmission line (40), in order to be able to set optimally an additional retransmission delay by the buffer (10) it is proposed to calculate the probable hold time of a data packet (1) immediately after arrival of a data packet (1) in the buffer (10). The additional retransmission delay by the buffer (10) is set based on the probable hold time of the data packets (1) in the buffer (10). To guarantee optimum setting of the retransmission delay, both the maximum detected probable hold time and the minimum detected probable hold time of the data packets (1) are used. This is achieved preferably by means of a minimum value detector and a maximum value detector which detect extreme values of the probable hold time occurring at specific time intervals.

  • Patent number: 7957455
    Abstract: A discrete sampling control signal, which influences the sampling time, from a sampling phase selection element is calibrated by definition of quantization intervals for a sampling time error signal. For this purpose, a received signal is shifted through a series of time shifts ?i in the signal path upstream of the sampling phase selection element. The sampling time errors ei associated with the respective time shifts ?i are measured. The quantization steps of the sampling control signal that are suitable for the sampling phase selection element are then determined from the relationship obtained between ?i and ei.

  • Patent number: 7948035
    Abstract: The present invention relates to a flash memory array. The flash memory array includes at least two word lines of gate electrode material. At least one of the word lines is connected through a first metal level to a discharge circuit, while other word line(s) may connect to a discharge circuit through a first and second metal level. The memory array further includes a shorting path between the word lines of the memory array. The shorting path is a high resistance layer of undoped gate electrode material. The resistance value of the gate electrode material is such that the word lines can be used to read, write, or erase without effecting each other, but that during the formation of a first metal level, as charges will build up on a first word line which requires a second metal level to connect to its discharge junction circuit, it will short the first word line to an adjacent second word line that has a connection to its junction circuit on the first metal level.
