In an integrated circuit component having a command interface to receive commands, a data interface to receive write data during a write-data reception interval, and first and second registers, control circuitry within the integrated circuit component responds to one or more of the commands by storing within the first register and the second register, respectively, a first control value that specifies a first termination to be applied to the data interface during the write-data reception interval, and a second control value that specifies a second termination to be applied to the data interface after the write-data reception interval transpires.
