Abstract
A method of operating a memory circuit includes generating a first current in response to a first voltage. The first current includes a first set of leakage currents and a first write current. The method further includes generating, by a tracking circuit, a second set of leakage currents configured to track the first set of leakage currents of the first column of memory cells, and mirroring the first current in a first path with a second current in a second path by a first current mirror. The second current includes the second set of leakage currents and a second write current. The first write current corresponds to the second write current. The first set of leakage currents corresponds to the second set of leakage currents.
