    摘要: Methods, systems, and devices for multiple transistor architecture for three-dimensional memory arrays are described. A memory device may include conductive pillars coupled with an access line using two transistors positioned between the conductive pillar and the access line. As part of an access operation for a memory cell coupled with the conductive pillar, the memory device may be configured to bias the access line to a first voltage and activate the two transistors using a second voltage to couple the conductive pillar with the access line. Additionally, the memory device may be configured to bias a gate of a first transistor and a gate of a second transistor coupling an unselected conductive pillar with the access line to a third and fourth voltage, respectively, which may deactivate at least one of the first or second transistor during the access operation and isolate the unselected conductive pillar from the access line.

    摘要: A semiconductor storage device of an embodiment includes a first conductive layer, a second conductive layer, a first conductive pillar, a first semiconductor layer, and a first storage layer. The first conductive layer extends in a first direction. The second conductive layer is along the first conductive layer in a third direction intersecting the first direction. The second conductive layer extends in the first direction. The first conductive pillar penetrates the first conductive layer and the second conductive layer in the third direction. The first semiconductor layer is in contact with the first conductive layer and the second conductive layer. The first semiconductor layer faces the first conductive pillar in the first direction. The first storage layer is between the first semiconductor layer and the first conductive pillar.

    摘要: Some embodiments include a memory cell having charge-trapping-material between a semiconductor channel material and a gating region. The charge-trapping-material includes silicon, nitrogen and trap-enhancing-additive. The trap-enhancing-additive includes one or more of carbon, phosphorus, boron and metal. Some embodiments include an integrated assembly having a stack of alternating first and second levels. The first levels include conductive structures and the second levels are insulative. Channel-material-pillars extend through the stack. Charge-trapping-regions are along the channel-material-pillars and are between the channel-material-pillars and the conductive structures. The charge-trapping-regions include a charge-trapping-material which contains silicon, nitrogen and trap-enhancing-additive. The trap-enhancing-additive includes one or more of carbon, phosphorus, boron and metal.
