SD (Secureity Digital) and eMMC (embedded MultiMedia Card) I/Os are non-volatile memory interface technologiesy with high bandwidth capabilities, which is particularlymainly developed for flash storage applications. M31 provides a silicon-proven SD/eMMC I/O in different a variety of process nodes, which . The SD/eMMC I/O complies with interface specifications of SD Association and JEDEC interface specifications and is available in two high-speed modes: to provide both SDR104 (SD I/O) and HS400 (eMMC I/O) high-speed modes.
