Abstract:
Systems, methods, and other embodiments associated with controlling a sense amplifier in a memory device are described. According to one embodiment, an apparatus includes a signal generator configured to generate a sense enable signal that activates a sense amplifier of a memory cell in a memory device. The apparatus includes a dummy memory cell connected to a current mirror circuit that is configured to detect a timing variation in the dummy memory cell from a predefined timing and to alter a timing of the sense enable signal based, at least in part, on the timing variation. The apparatus also includes a controller configured to modify the timing of the sense enable signal by selectively enabling one or more of a plurality of semiconductor gates in the current mirror circuit. The plurality of semiconductor gates are connected in parallel.
