Memory architecture and design methodology with adaptive read

摘要

An embodiment of a sense amplifier includes a sense circuit and a monitor circuit. The sense circuit is configured to convert a first signal that corresponds to data stored in a memory cell into a second signal that corresponds to the data, and the monitor circuit is configured to indicate a reliability of the second signal. The monitor circuit allows, for example, adjusting a parameter of a memory in which the memory cell is disposed to increase the read accuracy, and may also allow recognizing and correcting an error due to an invalid second signal.
