Abstract:
A memory circuit is provided comprising a plurality of bit cells coupled to a bit line that permits accessing information from each of the plurality of bit cells. A sense inverter is coupled to an output of the bit line. A keeper circuit has an output coupled to the bit line to compensate for current leakage from the plurality of bit cells. The keeper circuit may comprise an n-channel metal-oxide-silicon (NMOS) transistor in series with a p-channel metal-oxide-silicon (PMOS) transistor.
