  • Patent number: 11848048
    Abstract: Methods, systems, and devices for memory device decoder configurations are described. A memory device may include an array of memory cells and decoder circuits. The array may include one or more memory cells coupled with an access line, and a decoder circuit may be configured to bias the access line to one or more voltages. The decoder circuit may include a first transistor coupled with the access line and a second transistor coupled with the access line. The first transistor may be a planar transistor having a first gate electrode formed on a substrate, and the second transistor may be a trench transistor having a second gate electrode that extends into a cavity of the substrate, where a length of a first gate electrode may be greater than a length of the second gate electrode.

  • Publication number: 20220367714
    Abstract: Some embodiments include an integrated assembly having a first gate operatively adjacent a channel region, a first source/drain region on a first side of the channel region, and a second source/drain region on an opposing second side of the channel region. The first source/drain region is spaced from the channel region by an intervening region. The first and second source/drain regions are gatedly coupled to one another through the channel region. A second gate is adjacent a segment of the intervening region and is spaced from the first gate by an insulative region. A lightly-doped region extends across the intervening region and is under at least a portion of the first source/drain region. Some embodiments include methods of forming integrated assemblies.
