Abstract
A device is disclosed to include a memory cell, a first write assist unit and a second write assist unit. The first write assist unit provides a first operational voltage at a first pair of terminals of the memory cell. The second write assist unit provides at a second pair of terminals of the memory cell a second operational voltage different from the first operational voltage. In a write operation of the memory cell, the first write assist unit further generates a voltage difference between the first pair of terminals.
