  • Patent number: 7944750
    Abstract: A non-volatile memory device and method for manufacture and programing which does not require a control gate for the programing or erasure of the device. The memory device is comprised of two wells with the opposite conductivity type of the semiconductor body. In one of the wells is a source and drain well of the same conductivity type as of the body. A oxide is formed on the surface of the body on which a floating gate is formed. Specific voltages are applied to the source, drain, first well and second well region to program, erase and read the memory device.

  • Patent number: 7301194
    Abstract: A nonvolatile EEPROM cell having a double poly arrangement provides stored data without sense amplifiers, thereby reducing power requirements. The EEPROM cell has a floating gate in a first poly layer, and a control gate overlapping the floating gate in a second poly layer. This configuration allows for an area-efficient layout that is easily shrinkable as compared to prior art memory cells. In addition, stacking the control and floating gates results in higher capacitive coupling. The EEPROM cell also includes an access gate, a tunnel capacitor, and at least one inverter. In some embodiments, the EEPROM cell can be advantageously used to configure programmable logic without need for a conloading step.

  • Patent number: 7091077
    Abstract: Polysilicon or other material is directionally trimmed using two layers of photoresist and a photoresist etching process, such as ashing. A first layer of photoresist is patterned on a wafer. Portions of the first patterned photoresist are covered with a second layer of photoresist. The photoresist is trimmed to reduce the size of the exposed portions of the first patterned photoresist without reducing the size of the covered portions of the first patterned photoresist. The second layer of photoresist is removed. The selectively etched patterned first layer of photoresist is used as a process mask to define a structure in the underlying material. In a particular embodiment, the second photoresist covers endcap portions of gate photoresist. Directional trimming reduces the width of a polysilicon gate structure (i.e. gate length) over an active area of an FET, without reducing the length of original first patterned photoresist.

  • Patent number: 6711063
    Abstract: An EEPROM memory cell array architecture (50) that substantially eliminates leakage current to allow for reading memory cells (20) in a memory cell array of, for example, a CPLD at lower voltages than are possible with prior art architectures, thereby facilitating development of low voltage applications. This is accomplished by associating each wordline of the memory cell array with a ground transistor (26). On one embodiment, the ground transistor (26) can be a high voltage transistor, in which case the same high voltage control signal can control both the ground transistor (26) and the memory cell=s read transistor (32). In another embodiment, the ground transistor (26) is a low voltage transistor controlled by a separate low voltage control signal.
