Abstract
Integrated circuits including semiconductor memory devices, read assist circuits for semiconductor memory devices, and methods for operating such circuits are provided. In an embodiment, a read assist circuit for use in a semiconductor memory device is provided. The read assist circuit includes a first drive device for driving a wordline of the semiconductor memory device to a wordline driving voltage. The first drive device operates at a first current. The read assist circuit also includes a second drive device for maintaining the wordline of the semiconductor memory device at the wordline driving voltage. The second drive device operates at a second current lower than the first current.
