Abstract

A write driver circuit comprising a first transistor comprising a first source/drain terminal coupled to a first output, a second source/drain terminal coupled with a first reference potential, and a gate terminal; a second transistor comprising a first source/drain terminal coupled to a second output, a second source/drain terminal coupled with the first reference potential, and a gate terminal; and a gate voltage generator coupled to the gate terminals of the first and second transistors.
