Abstract
A circuit includes a write driver, a data circuit, a memory cell, a tracking write buffer, a tracking write driver, and a tracking cell. The circuit is configured that, during a write operation of the memory cell based on a clock signal, the write driver circuit is configured to generate a write control signal to control the memory cell; the data circuit is configured to provide write data to the memory cell; the tracking write buffer is configured to generate a tracking write control signal; and the tracking write driver is configured to generate a tracking write data signal to be transferred to the tracking cell. The tracking cell is configured to adjust a signal at a first node of the tracking cell based on a logical value of the tracking write data signal in response to the tracking write control signal.
