Abstract
A circuit includes a first power node that receives a first operational voltage having a first operational voltage level and a second power node that receives a second operational voltage having a second operational voltage level different from the first operational voltage level. A memory cell is coupled with the first power node, the memory cell configured to store a logic value, and a tracking cell is coupled with the second power node, the tracking cell configured to generate a signal having a timing responsive to the second operational voltage level. The circuit is configured to read the logic value of the memory cell based on the signal.
