    摘要: A array of multi-bit Read Only Memory (ROM) cells is in a semiconductor substrate of a first conductivity type with a first concentration. Each ROM cell has a first and second regions of a second conductivity type spaced apart from one another in the substrate. A channel is between the first and second regions. The channel has three portions, a first portion, a second portion and a third portion. A gate is spaced apart and is insulated from at least the second portion of the channel. Each ROM cell has one of a plurality of N possible states, where N is greater than 2. The state of each ROM cell is determined by the existence or absence of extensions or halos that are formed in the first portion of the channel and adjacent to the first region and/or in the third portion of the channel adjacent to the second region. These extensions and halos are formed at the same time that extensions or halos are formed in MOS transistors in other parts of the integrated circuit device, thereby reducing cost. The array of ROM cells are arranged in a plurality of rows and columns, with ROM cells in the same row having their gates connected together. ROM cells in the same column have the first regions connected in a common first column, and second regions connected in common second column. Finally, ROM cells in adjacent columns to one side share a common first column, and cells in adjacent columns to another side share a common second column.

The vertical NROM cell and device has a first region and a second region spaced apart from one another by a channel. A dielectric is spaced apart from the channel to capture charges injected from the channel onto the dielectric. A gate is positioned over the dielectric and spaced apart therefrom and controls the flow of current through the channel. In the improvement of the present invention, a portion of the channel is substantially perpendicular to the top planar surface of the substrate. Methods for making the vertical NROM cell and array are also disclosed.

    摘要: A non-volatile memory cell has a single crystalline semiconductive material, such as single crystalline silicon, of a first conductivity type. A first and a second region each of a second conductivity type, different from the first conductivity type, spaced apart from one another is formed in the semiconductive material. A channel region, having a first portion, and a second portion, connects the first and second regions for the conduction of charges. A dielectric is on the channel region. A floating gate, which can be conductive or non-conductive, is on the dielectric, spaced apart from the first portion of the channel region. The first portion of the channel region is adjacent to the first region, with the first floating gate having generally a triangular shape. The floating gate is formed in a cavity. A gate electrode is capacitively coupled to the first floating gate, and is spaced apart from the second portion of the channel region. The second portion of the channel region is between the first portion and the second region. A bi-directional non-volatile memory cell has two floating gates each formed in a cavity. A method of making the non-volatile memory cell and the array are also disclosed.

    摘要: A self aligned method of forming a semiconductor memory array of floating gate memory cells in a semiconductor substrate has a plurality of spaced apart isolation regions on the substrate substantially parallel to one another. An active region is between each pair of adjacent isolation regions. The active and isolation regions are formed in parallel and in the column direction. In the row direction, strips of spaced apart silicon nitride are formed. A source line plug is formed between adjacent pairs of silicon nitride and is in contact with a first region in the active regions, and the isolation regions. The strips of silicon nitride are removed and isotropically etched. In addition, the materials beneath the silicon nitride are also isotropically etched. Polysilicon spacers are then formed in the row direction parallel to the source line plug and adjacent to the floating gates. A second region is formed between adjacent, spaced apart, control gates. A bit line is formed in the bit line direction contacting the second region in the space between the control gates.
