摘要： A processor circuit sends a read request. A clock signal of the processor circuit corresponds to a first counting value. A memory circuit stores data and sends a data strobe signal in response to the read request. The data strobe signal corresponds to a second counting value. The processor circuit includes a selector circuit and a feedback circuit. The selector circuit selects and outputs a flag signal from a plurality of flag control signals according to the second counting value. The feedback circuit generates an enable signal according to a set signal associated with the first counting value, the flag signal associated with the second counting value, and a data strobe gate signal, and generates the data strobe gate signal according to the enable signal and the data strobe signal. The processor circuit reads the data according to the data strobe gate signal.

摘要： A memory physical layer interface circuit electrically connected between a memory controller and a memory device is provided. The memory physical layer interface circuit includes a dock generation module and first-in-first-out (FIFO) modules. The clock generation module generates a reference clock signal and output related clock signals. The reference clock signal is transmitted to the memory device. Each of the FIFO modules writes the input information therein transmitted by the memory controller according to a write-related clock signal and retrieves the input information therefrom according to one of the output related clock signals to generate an output signal. The output signal is transmitted to the memory device to operate the memory device. The write-related clock signal is generated by dividing a frequency of one of the output related clock signals.
