  • Patent number: 12148802
    Abstract: A driver circuit for a three-dimensional (3D) memory device has a field management structure electrically coupled to a gate conductor. The field management structure causes an electric field peak in a vertical channel of the 3D memory device when a voltage differential exists between the source conductor and the drain conductor and the gate conductor is not biased. The electrical field peak can adjust the electrical response of the driver circuit, enabling the circuit to have a higher breakdown threshold voltage and improved drive current. Thus, the driver circuit can enable a scalable vertical string driver that is above the memory array instead of under the memory array circuitry.

  • Patent number: 12120878
    Abstract: An integrated circuit memory includes a first memory block and an adjacent second memory block. The first memory block comprises a first memory pillar around which a first memory cell is formed. The second memory block comprises a second memory pillar around which a second memory cell is formed. An isolation or slit area between the first and second memory blocks electrically isolates the first and second memory blocks. In an example, the slit area comprising a slit pillar around which no memory cells are formed. The slit pillar is a dummy pillar, and insulator material electrically isolates the slit pillar from a Word Line (WL) through which it passes. The isolation layer electrically can also isolate a (WL) of the first memory block from a corresponding WL of the second memory block. In an example, the slit pillar and the memory pillars have at least in part similar structures.

  • Patent number: 12089412
    Abstract: A driver circuit for a three-dimensional (3D) memory device has a super junction structure as a field management structure. The super junction structure could be referred to as an extended junction structure, which distributes the electrical field of the junction between the vertical channel and the gate conductor for a string driver. The vertical channel includes a channel conductor to connect vertically between a source conductor and a drain conductor. The extended junction structure extends in parallel with the vertical channel conductor, extending vertically toward the drain conductor, having a height greater than a height of the gate conductor.
