Abstract
Some embodiments include an integrated assembly having an access transistor. The access transistor has a first source/drain region gatedly coupled with a second source/drain region. A digit line is coupled with the first source/drain region. A charge-storage device is coupled with the second source/drain region through an interconnect. The interconnect includes a length of a semiconductor material. A protective transistor gates a portion of the length of the semiconductor material.
