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. |

| 2007-03-12 | Supporting two SD devices with a single SD bus host controller The SanDisk iNAND Module is a BGA-packaged embedded product with an SD interface that can be soldered directly to the PCB. There has been an increasing demand from host manufacturers that already support one SD device, to leverage their design and add another SD device. For instance, designers could add an SD slot to a host with embedded iNAND. Hosts containing SD slots could have the option of adding an embedded SD-based device such as a SanDisk iNAND Module. This application note will provide options for designers who wish to incorporate an iNAND Module when the host controller does not support two SD interfaces. |
