Abstract
Embodiments of the disclosure provide systems and methods for transmitting clock signals asynchronously to dual-port memory cells. A system according to embodiments of the disclosure may include a source clock configured to generate a clock signal, a dual-port memory cell having a first input port, and a second input port coupled to the source clock. A clock tuner coupled between the source clock and the first input port of the dual-port memory cell delays the clock signal by one of a plurality of delay times and transmits the clock signal to the first input port.
