    摘要: A NAND-type flash memory device includes asymmetric floating gates overlying respective wordlines. A given floating gate is sufficiently coupled to its respective wordline such that a large gate (i.e., wordline) bias voltage will couple the floating gate with a voltage which can invert the channel under the floating gate. The inversion channel under the floating gate can thus serve as the source/drain. As a result, the memory device does not need a shallow junction, or an assist-gate. In addition, the memory device exhibits relatively low floating gate-to-floating gate (FG-FG) interference.

    摘要: A phase change random access memory PCRAM device is described suitable for use in large-scale integrated circuits. An exemplary memory device has a pipe-shaped first electrode formed from a first electrode layer on a sidewall of a sidewall support structure. A sidewall spacer insulating member is formed from a first oxide layer and a second, “L-shaped,” electrode is formed on the insulating member. An electrical contact is connected to the horizontal portion of the second electrode. A bridge of memory material extends from a top surface of the first electrode to a top surface of the second electrode across a top surface of the sidewall spacer insulating member.

    摘要: An air tunnel floating gate memory cell includes an air tunnel defined over a substrate. A first polysilicon layer (floating gate) is defined over the air tunnel. An oxide layer is disposed over the first polysilicon layer such that the oxide layer caps the first polysilicon layer and defines the sidewalls of the air tunnel. A second polysilicon layer, functioning as a word line, is defined over the oxide layer. A method for making an air tunnel floating gate memory cell is also disclosed. A sacrificial layer is formed over a substrate. A first polysilicon layer is formed over the sacrificial layer. An oxide layer is deposited over the first polysilicon layer such that the oxide layer caps the first polysilicon layer and defines the sidewalls of the sacrificial layer. A hot phosphoric acid (H3PO4) dip is used to etch away the sacrificial layer to form an air tunnel.
