Integrated assemblies having conductive material along three of four sides around active regions, and methods of forming integrated assemblies

An integrated assembly, comprising:

• an array of vertically-extending active regions;
• each of the active regions comprising a lower source/drain region, an upper source/drain region, and a channel region vertically between the upper and lower source/drain regions;
• each of the active regions being contained within a four-sided area;
• first conductive structures extending along rows of the array;
• the first conductive structures having comb-shaped configurations with shafts of the comb-shaped configurations extending linearly along the rows and being along first sides of the four-sided areas, and with teeth of the comb-shaped configurations projecting from the shafts and being along second and third sides of the four-sided areas;
• the comb-shaped configurations being adjacent the channel regions;
• second conductive structures under the active regions and extending along columns of the array;
• the second conductive structures being electrically coupled with the lower source/drain regions;
• and
• storage-elements electrically coupled with the upper source/drain regions.
