Abstract
In one embodiment, a read port circuit includes a precharge circuit configured to precharge a first node in the read port circuit and a pulldown circuit coupled to the first node. The pulldown circuit is configured to conditionally discharge the first node responsive to a first plurality of wordline signals and a first plurality of data signals. Each of the wordline signals corresponds to a respective memory cell of a first plurality of memory cells, and each of the data signals corresponds to a respective memory cell and represents data stored in the respective memory cell. In some embodiments, the read port circuit may be included in a register file in an integrated circuit that also includes logic circuitry configured to generate an address for a read port.
