Abstract
An example method to track bit cell current in a memory architecture. An example method disclosed herein includes generating a first reference current dependent on bit cell temperature. The example method includes generating a second reference current dependent on bit cell voltage and supplying a third reference current of constant magnitude. In examples disclosed herein, the example method involves summing the first reference current, the second reference current, and the third reference current. The example method includes determining, with a sense amplifier, a bit cell logic state based on the first reference current, the second reference current, and the third reference current.
