  • Patent number: 10622450
    Abstract: A 3D memory structure including a modified floating gate and dielectric layer geometry is described. In embodiments, a memory cell includes a channel region and a floating gate where a length of the floating gate along a direction of the channel region is substantially longer than a length of the floating gate along an orthogonal direction along the channel region. A control gate adjacent to the floating gate extends at least as long as the control gate along the direction of the channel region and includes a tapered edge extending away from the channel region towards the control gate. In embodiments, a dielectric layer between the control gate and the floating gate may follow the tapered edge along the floating gate and form a discrete region proximate to the floating gate to at least partially insulate the floating gate from an adjacent memory cell. Other embodiments are disclosed and claimed.
