Abstract:
1. A shifter can avoid utilizing a partial pulse, comprising: a first shifting stage, for utilizing an external clock signal to sample a command signal to generate a first sampled command signal; a second shifting stage, for utilizing the external clock signal to sample the first sampled command signal to generate a second sampled command signal; a third shifting stage, for utilizing a command triggering clock signal to generate a third sampled command signal according to the second sampled command signal; and a command triggering clock signal generating circuit, for generating the command triggering clock signal according to the command signal; where the first shifting stage does not utilize the command triggering clock signal to sample the command signal, the second shifting stage does not utilize the command triggering clock signal to sample the first sampled command signal, and the third shifting stage does not utilize the external clock signal to generate the third sampled command signal according to the second sampled command signal.
