  • Publication number: 20030015753
    Abstract: A process for forming an integrated circuit calls for the provision of at least one matrix of non-volatile memory cells including an intermediate dielectric multilayer comprising a lower silicon oxide layer, an intermediate silicon nitride layer and an upper silicon oxide layer. The process calls for the simultaneous provision in zones peripheral to the memory cells of at least one first and one second transistor type each having a gate dielectric of a first and a second thickness respectively. After formation of the floating gate of the cells with a gate oxide layer and a polycrystalline silicon layer and the formation of the lower silicon oxide layer and of the intermediate silicon nitride layer, the process in accordance with the present invention includes removal of said layers from the zones peripheral to the matrix, and formation of a first silicon oxide layer over the substrate in the areas of both types of transistor.

  • Patent number: 6507067
    Abstract: A flash EEPROM having an array of memory cells which include a common source line connecting together source electrodes of the memory cells. A resistive feedback element is coupled in series between the common source line and a positive potential when the memory cells must be electrically erased. The Flash EEPROM includes a voltage limiting circuit coupled to the common source line for limiting the potential of the common source line to be prescribed maximum value lower than the positive potential.
