Abstract
A multi-port memory cell of a multi-port memory array includes a first inverter that inverter is disabled by a first subset of write word lines and a second inverter, cross coupled with the first inverter, wherein the second inverter is disabled by a second subset of the plurality of write word lines. A first selection circuit has data inputs coupled to a first subset of a plurality of write bit lines, selection inputs coupled to the first subset of the plurality of write word lines, and an output coupled to the input of the second inverter. The second selection circuit has data inputs coupled to a second subset of the plurality of write bit lines, selection inputs coupled to the second subset of the plurality of write word lines, and an output coupled to the input of the first inverter.
