Abstract
A memory assist apparatus includes a detection circuit and a compensation circuit. The detection circuit is configured to provide a detection signal indicating whether a bit line configured to provide read access to a data bit stored at a memory bit cell has a voltage below a predetermined threshold. The compensation circuit is configured to pull down the voltage of the bit line if the detection signal indicates that the voltage of the bit line is below the predetermined threshold.
