Abstract:
An exemplary embodiment provides an equalizer adjustment method. The method includes: performing a handshake operation to establish a connection with a host system by a memory storage device; in the handshake operation, receiving a first signal from the host system and performing a first modulation on the first signal by the adaptive equalizer; after the handshake operation is ended, receiving a second signal from the host system and performing a second modulation on the second signal according to a modulation result of the first modulation by the adaptive equalizer to compensate the second signal; and adjusting the adaptive equalizer according to a modulation result of the second modulation.
Abstract:
A channel switching device, a memory storage device and a channel switching method are provided. The channel switching device includes a signal analysis module and a switch module. The signal analysis module is configured to analyze non-power signal from at least one of a plurality of connection interface units of the memory storage device. The switch module is configured to turn on a first channel coupled to a first connection interface unit among the connection interface units of the memory storage device according to an analysis result of the non-power signal, where the first channel which is turned on is for receiving first input signal from the first connection interface unit or transmitting first output signal to the first connection interface unit. Therefore, a probability of mistakenly enabling or disabling a specific connection interface unit of a memory storage device can be reduced.
Abstract:
A signal modulation method, an adaptive equalizer and a memory storage device are provided. The method includes: receiving a first signal; performing a first modulation on the first signal based on a first power mode to generate a second signal having a first eye-width; performing a second modulation based on a second power mode to generate the second signal having a second eye-width; determining whether the first eye-width and the second eye-width meet a first condition; if yes, performing a third modulation based on the first power mode to generate the second signal having a third eye-width; otherwise, performing the third modulation based on the second power mode to generate the second signal having the third eye-width. Therein, a power consumption of performing the second modulation is less than that of performing the first modulation. Therefore, an efficiency of the adaptive equalizer may be improved.
