Apparatus for adapting interface type of peripheral device and method thereof

Abstract

The present invention discloses a memory control device and method compatible to multiple types of interface the memory control device comprises: a multi-interface physical layer circuit configured to couple to a host, to receive a differential signal from the host, to detect at least one of characteristics of the differential signal to generate a physical layer output signal and to generate a physical layer output signal according to a detected result, wherein a frequency of the differential signal is higher than hundreds of KHz; and a processing circuit, coupled between the multi-interface physical layer circuit and a memory module, configured to receive the physical layer output signal from the multi-interface physical layer circuit, to determine the differential signal complies with one of a specification of an first type of interface and that of a second type of interface according to the physical layer output signal, and to adapt an operation mode of the memory control device to one of the multiple types of interface according to a determined result; wherein the memory control device operates in the adapted operation mode to receive at least one access command from the host to access the memory module.
