Abstract
A device including a memory cell and write assist circuit is disclosed. The memory cell includes a first inverter and a second inverter cross-coupled with the first inverter. The first inverter is operated with a first operational voltage and a third operational voltage, and the second inverter is operated with a second operational voltage and a fourth operational voltage. The write assist circuit is coupled to the memory cell. During a write operation of the memory cell, the write assist circuit is configured to adjust a voltage level of the first operational voltage, the second operational voltage, the third operation voltage, the fourth operation voltage, or a combination thereof, by a bias voltage difference.
