Various implementations described herein may refer to and may be directed to using port modes with memory. In one implementation, a memory device may include access control circuitry used to selectively activate one of a plurality of first word-lines based on first address signals from a first access port, and used to selectively activate one of a plurality of second word-lines based on assigned address signals. The access control circuitry may include address selection circuitry configured to select the assigned address signals based on a port mode signal, where the address selection circuitry selects the first address signals as the assigned address signals when the port mode signal indicates a single port mode, and where the address selection circuitry selects second address signals from a second access port as the assigned address signals when the port mode signal indicates a dual port mode.
