  • Publication number: 20250142827
    Abstract: Some embodiments include an integrated structure having a conductive material, a select device gate material over the conductive material, and vertically-stacked conductive levels over the select device gate material. Vertically-extending monolithic channel material is adjacent the select device gate material and the conductive levels. The monolithic channel material contains a lower segment adjacent the select device gate material and an upper segment adjacent the conductive levels. A first vertically-extending region is between the lower segment of the monolithic channel material and the select device gate material. The first vertically-extending region contains a first material. A second vertically-extending region is between the upper segment of the monolithic channel material and the conductive levels. The second vertically-extending region contains a material which is different in composition from the first material.

  • Publication number: 20250142820
    Abstract: Some embodiments include an integrated assembly with a semiconductor channel material having a boundary region where a more-heavily-doped region interfaces with a less-heavily-doped region. The more-heavily-doped region and the less-heavily-doped region have the same majority carriers. The integrated assembly includes a gating structure adjacent the semiconductor channel material and having a gating region and an interconnecting region of a common and continuous material. The gating region has a length extending along a segment of the more-heavily-doped region, a segment of the less-heavily-doped region, and the boundary region. The interconnecting region extends laterally outward from the gating region on a side opposite the semiconductor channel region, and is narrower than the length of the gating region. Some embodiments include methods of forming integrated assemblies.

  • Patent number: 11864386
    Abstract: A memory array comprises vertically-alternating tiers of insulative material and memory cells. The memory cells individually comprise a transistor comprising first and second source/drain regions having a channel region there-between and a gate operatively proximate the channel region. The individual memory cells comprise a capacitor comprising first and second electrodes having a capacitor insulator there-between. The first electrode electrically couples to the first source/drain region. Wordline structures extend elevationally through the insulative material and the memory cells of the vertically-alternating tiers. Individual of the gates that are in different of the memory cell tiers directly electrically couple to individual of the wordline structures. Sense-lines electrically couple to multiple of the second source/drain regions of individual of the transistors. Other embodiments are disclosed.
