  • Patent number: 11936052
    Abstract: Provided is a fluorine-doped tin oxide support, a platinum catalyst for a fuel cell having the same, and a method for producing the same. Also described is a high electrical conductivity and electrochemical durability by doping fluorine to the tin oxide-based support through an electrospinning process. Thus, while resolving a degradation issue of the carbon support in the conventional commercially available platinum/carbon (Pt/C) catalyst, what is designed is to minimize an electrochemical elution of dopant or tin, which is a limitation of the tin oxide support itself and has excellent performance as a catalyst for a fuel cell.

  • Patent number: 9431126
    Abstract: A non-volatile memory device and method for programming cells using repeated pulses of program voltages, with interleaved read operations to determine the level of read current, until the desired programming state is achieved. Each successive program pulse has one or more program voltages increased by a step value relative to the previous pulse. For a single level cell type, each cell is individually removed from the programming pulses after reaching a first read current threshold, and the step value is increased for one or more kicker pulses thereafter. For a multi-level cell type, the step value drops after one of the cells reaches a first read current threshold, some cells are individually removed from the programming pulses after reaching a second read current threshold while others are individually removed from the programming pulses after reaching a third read current threshold.

  • Patent number: 9275748
    Abstract: A method of reading a memory device having rows and columns of memory cells formed on a substrate, where each memory cell includes spaced apart first and second regions with a channel region therebetween, a floating gate disposed over a first portion of the channel region, a select gate disposed over a second portion of the channel region, a control gate disposed over the floating gate, and an erase gate disposed over the first region. The method includes placing a small positive voltage on the unselected source lines, and/or a small negative voltage on the unselected word lines, during the read operation to suppress sub-threshold leakage and thereby improve read performance.

  • Patent number: 8576648
    Abstract: A method of decreasing the test time to determine data retention (e.g. leakage current) of a memory cell having a floating gate for the storage of charges thereon. The memory cell is characterized by the leakage current having a rate of leakage which is dependent upon the absolute value of the voltage of the floating gate. The memory cell is further characterized by a first erase voltage and a first programming voltage, applied during normal operation, and a first read current detected during normal operation. The method applies a voltage greater than the first erase voltage or greater than the first programming voltage, to over erase the floating gate. The memory cell including the floating gate is subject to a single high temperature bake. The memory cell is then tested for data retention of the floating gate based on the single high temperature bake.

  • Patent number: 8488388
    Abstract: A non-volatile memory cell includes first and second regions and a channel region therebetween, a word line gate over a first portion of the channel region, a floating gate over another portion of the channel region and adjacent to the word line gate, a coupling gate over the floating gate, and an erase gate adjacent to the floating gate on an opposite side to the word line gate and over the second region. Programming the memory cell includes applying a first positive voltage to the word line gate, applying a voltage differential between the first and second regions, applying a second positive voltage to the coupling gate (where the voltages and the voltage differential are applied substantially at the same time), and applying a third positive voltage to the erase gate after a period of delay from the application of the first and second positive voltages and the voltage differential.

  • Patent number: 7269446
    Abstract: Disclosed is a hands-free signal processing device in a mobile communication terminal. More particularly, disclosed is a hands-free signal processing device in a mobile communication terminal, which may separate hands-free signals, such as a microphone signal and an interrupt signal generated in a hands-free device, by using transistors, and properly process the hands-free signals. According to the present invention, current consumption caused by a hands-free device can be minimized by converting AUX_MIC signal into pulse and by using the pulse as a reference pulse of the hands-free device. Further, a talk-key interrupt signal of a hands-free device can be correctly detected while incoming/outgoing calls are connected. Thus, a problem in timing can be solved and a proper reaction to the talk-key interrupt signal of a hands-free device can be achieved.
