  • Computing apparatus employing dynamic memory cell structures
    Patent number: 8604532
    Abstract: A dynamic random access memory cell is disclosed that comprises a capacitive storage device and a write access transistor. The write access transistor is operatively coupled to the capacitive storage device and has a gate stack that comprises a high-K dielectric, wherein the high-K dielectric has a dielectric constant greater than a dielectric constant of silicon dioxide. Also disclosed are a memory array using the cells, a computing apparatus using the memory array, a method of storing data, and a method of manufacturing.
    Type: Grant
