Abstract
A circuit for adjusting a signal length is adapted for a memory device. The circuit adjusts a signal length of an ATD signal. The circuit includes a timing module, an encoding module and a logical control unit. Wherein, the timing module generates a plurality of timing signals according a pulse generated by the ATD signal. The encoding module is coupled to one of the data lines of the memory device. The timing signals are registered and encoded to generate a time value according to the status of the data output from the memory device. In addition, the logic control unit compares the present time value and the previous time value to generate a comparison result. The signal length of the ATD signal is adjusted according to the comparison result.
