Abstract
A device is disclosed. The device includes a first tracking control line, a first tracking circuit, a first sense circuit, and a precharge circuit. The first tracking control line is configured to transmit a first tracking control signal. The first tracking circuit is configured to generate, in response to the first tracking control signal, a first tracking signal associated with first tracking cells in a memory array. The first sense circuit is configured to receive the first tracking signal, and is configured to generate a first sense tracking signal in response to the first tracking signal. The precharge circuit is configured to generate, in response to a rising edge of the first sense tracking signal and a falling edge of a read enable delayed signal, a precharge signal for precharging data lines associated with memory cell in the memory array. A method is also disclosed herein.
