Inventor(s)Garrett, Jr.; Billy Wayne (Mountain View, CA); Dillon; John B. (late of Palo Alto, CA); Dillon; by Nancy David (Marshall, VA); Ching; Michael Tak-Kei (Sunnyvale, CA); Stonecypher; William F. (San Jose, CA); Chan; Andy Peng-Pui (San Jose, CA); Griffin; Matthew M. (Mountain View, CA)
AbstractA semiconductor memory device including an array of memory cells. The memory device includes a first output driver coupled to a first output terminal, and a second output driver coupled to a second output terminal. The memory device further includes a voltage divider coupled between the first and second output terminals, to generate a control voltage based on a voltage level present on the first output terminal and a voltage level present on the second output terminal. The memory device further includes a comparator, coupled to the voltage divider, to compare the control voltage with a reference voltage, wherein an amount of voltage swing of the first output driver is adjusted based on the comparison between the control voltage and the reference voltage.
