Abstract
A technique for operating a memory circuit that improves performance of the memory circuit and/or power consumption for at least some operating points of the memory circuit includes adjusting a number of operational pipeline stages at least partially based on an operating point of the memory. In at least one embodiment of the invention, a method for operating a memory circuit includes selecting a mode of operating the memory circuit at least partially based on a feedback signal generated by the memory circuit. The technique includes operating the memory circuit using a number of pipeline stages based on the selected mode of operation of the memory circuit. In at least one embodiment of the invention, the technique includes sensing a timing margin associated with an individual pipeline stage and generating the feedback signal based thereon.
