  • SONOS memory array with improved read disturb characteristic
    Patent number: 7423912
    Abstract: A PMOS non-volatile memory array using SONOS transistors having program and erase threshold voltages for representing digital logic states of zero and one and selected to optimize read disturb characteristics. The threshold voltages are linearly convergent and separated by at least 0.5 volts for a charge retention time of at least 10 years, with the threshold voltages defining a window wherein a read voltage for selected memory transistors can be held flat and not intersect the threshold voltages. The lower threshold is selected to be at a zero charge state for one of the two logic levels of the memory.
    Type: Grant

  • Method for decreasing low density lipoprotein
    Patent number: 6841547
    Abstract: The present invention relates to a method for decreasing elevated serum/plasma LDL-cholesterol levels or LDL-cholesterol levels and CRP levels in a mammal in need thereof. The methods comprises administering an effective amount of a tetracycline formulation. In one embodiment, the tetracycline formulation is a non-antibacterial tetracycline. In another embodiment, the tetracycline formulation is an antibacterial tetracycline at a sub-antibacterial amount.
