Abstract

A memory storage device having a clock and data recovery circuit module are provided. The module includes sampling circuits, a first logic circuit module, a delay circuit module, a second logic circuit module, a frequency adjustment circuit and a clock control circuit. The sampling circuits sample a data signal according to reference clocks. The first logic circuit module performs a first logic operation according to a sampling result. The delay circuit module delays a result of the first logic operation. The second logic circuit module performs a second logic operation according to said result and the delayed first logic result. The frequency adjustment circuit outputs a frequency adjustment signal according to a result of the second logic operation, and the clock control circuit performs a phase locking accordingly. Therefore, a circuit complexity of the clock and data recovery circuit module may be reduced.
