Abstract
Buffers, integrated circuits, apparatuses, and methods for adjusting drive strength of a buffer are disclosed. In an example apparatus, the buffer includes a driver. The driver includes a pull-up circuit coupled to a supply voltage node and an output node, and also includes a pull-down circuit coupled to a reference voltage node and the output node. A drive adjust circuit is coupled to at least one of the pull-up circuit and the pull-down circuit, with the drive adjust circuit configured to receive a feedback signal and, based at least in part on the feedback signal, adjust a current conducted through the at least one of the pull-up and pull-down circuits.
