Abstract
An apparatus is disclosed, including a plurality of memory cells, in which a given memory cell is coupled to a true bit line, a complement bit line, and a power supply signal. The apparatus also includes a pre-charge circuit that is configured to charge, for a first duration, the true bit line and the complement bit line to a voltage level that is less than a voltage level of the power supply signal. The pre-charge circuit is also configured to maintain, for a second duration that is longer than the first duration, the voltage level on the true bit line and the complement bit line.
