Abstract: A memory module with improved timing adaptivity of sensing amplification, comprises at least one sensing amplifier, a tracking word line, a tracking bit line and a pulse-width controller. The tracking word line comprises a front node and an end node. Each said sensing amplifier is enabled/disabled when an enabling signal is activated/deactivated. The pulse-width controller is coupled to the tracking bit line, the front node and the end node. When a voltage of the tracking bit line changes to a predetermined voltage, the pulse-width controller activates the enabling signal, and causes a voltage of the front node to change. When the voltage of the front node changes, the tracking word line causes a voltage of the end node to change after a first delay time. When the voltage of the end node changes, the pulse-width controller deactivates the enabling signal after a second delay time.

Abstract: A clock and data recovery circuit includes a phase detector (PD), a phase frequency detector (PFD), a multiplexer circuit, a conversion stage and an oscillator. The PD detects a difference in phase between a data signal and an oscillating signal to generate a first set of error signals. The PFD detects a difference in phase and frequency between a reference clock signal and the oscillating signal to generate a second set of error signals. The multiplexer circuit selectively outputs the first set of error signals or the second set of error signals as a third set of error signals according to a selection signal. The conversion stage determines a set of gains according to the selection signal, and converts the third set of error signals with the set of gains to generate a set of input signals. The oscillator generates the oscillating signal according to the set of input signals.
