    摘要: An EEPROM memory cell uses PMOS type floating gate transistor formed in a n-well, where the floating gate is routed over a p− diffused region formed in the n-well to form a control capacitor. The PMOS floating gate transistor uses a p-type diffused region below the p+ active region forming the drain to provide a higher breakdown voltage. Cell programming can be performed through hot-electron injection, with the electric field across the control capacitor to aid injection into the floating gate. FN erasure is achieved by taking the potential of the n-well to the programming voltage while holding the potential of the control capacitor at a low voltage.

    摘要: An array structure of single-level poly NMOS EEPROM memory cells and method of operating the array is discussed implemented in a higher density embedded EEPROM layout that eliminates the use of high voltage transistors from the array core region. If they are utilized, the high voltage transistors are moved to row and column drivers in the periphery region to increase array density with little or no added process complexity to allow economic implementation of larger embedded SLP EEPROM arrays. During program or erase operations of the array, the method provides a programming voltage for the selected memory cells of the array, and a half-write (e.g., mid-level) voltage to the remaining unselected memory cells to avoid disturbing the unselected memory cells of the array.

    摘要: The leakage current of an OTP-EPROM cell formed using buried channel PMOS technology can be reduced. The reduction in leakage current of the OTP-EPROM can be achieved by blocking implantation of the Vtp implant into a channel region of an n-well that substantially underlies a floating gate structure. The Vtp implant can be blocked by providing a mask overlying the surface of the channel region of the n-well during implantation of the Vtp implant.
