Abstract
A circuit and a method for controlling the write timing of a non-volatile memory are provided. The method includes the following steps. First, a resistance state switching of at least one memory cell of the non-volatile memory executing a writing operation is monitored to output a control signal. The memory cell stores data states with different resistance states. A write timing is input to the memory cell through a timing control line. Next, the write timing is generated based on a clock signal and the control signal. The write timing is enabled at the beginning of a cycle of the clock signal, and is disabled when the memory cell finishes the resistance state switching.
