Some embodiments include an integrated assembly having active-region-pillars. Each of the active-region-pillars has contact regions. The contact regions include a pair of storage-element-contact-regions, and include a digit-line-contact-region between the storage-element-contact-regions. The active-region-pillars include silicon. Wordlines are along the active-region-pillars and extend along a first direction. Cobalt silicide is directly against the silicon of one or more of the contact regions. Metal-containing material is directly against the cobalt silicide. Digit-lines are electrically coupled with the digit-line-contact-regions and extend along a second direction which crosses the first direction. Storage-elements are electrically coupled with the storage-element-contact-regions. Some embodiments include methods of forming integrated assemblies.
