Abstract
A circuit includes: a first data line; a second data line; a write driver including first and second transistors; a first switch connected in series with the first transistor to form a first series-connected pair; a second switch in series with the second transistor to form a second series-connected pair; and a level shifter which includes the first and second transistors. The first series-connected pair is coupled between a first voltage node and the first data line. The second series-connected pair is coupled between the first voltage node and the second data line. Gate terminals of the first and second transistors are correspondingly cross-coupled with the second and first data lines.
