What is a memory interface?
An external memory interface is a bus protocol for communication from an IC, such as a microprocessor, to an external memory device located on a circuit board. Internal memory interfaces apply to communication with on-chip memory. The asynchronous External Memory Interface (EMIF) is a Texas Instruments IC bus used in their DSPs and digital media SoCs.
