External memory interface
BUS PROTOCOL
EMIF; External Memory Interface
An external memory interface is a bus protocol for communication from an integrated circuit, such as a microprocessor, to an external memory device located on a circuit board. The memory is referred to as external because it is not contained within the internal circuitry of the integrated circuit and thus is externally located on the circuit board.
External memory algorithm
ALGORITHM TO PROCESS DATA THAT IS TOO LARGE TO FIT INTO A COMPUTER'S MAIN MEMORY AT ONE TIME, OPTIMIZED TO EFFICIENTLY FETCH AND ACCESS DATA STORED IN SLOW BULK MEMORY (E.G. HARD DRIVES, TAPE DRIVES, REMOTE NETWORK)
Out-of-core; External memory algorithms; I/O algorithms; I/O algorithm; External memory model; I/O model; Disk access model; Out-of-core algorithm; Cache-aware model
In computing, external memory algorithms or out-of-core algorithms are algorithms that are designed to process data that are too large to fit into a computer's main memory at once. Such algorithms must be optimized to efficiently fetch and access data stored in slow bulk memory (auxiliary memory) such as hard drives or tape drives, or when memory is on a computer network.

Examples of use of external memory
1. You‘ll also notice a unique hardware feature on the front of the C8180: a LightScribe drive that lets you archive your data directly from a USB key or an external memory card to a CD/DVD.
2. While you might think the USB port is used for looking at some JPEGs or listening to MP3s, actually its only purpose is to serve as external memory for advanced Blu–ray features––which is why the port is labeled "EXT." You‘ll need to connect a USB drive for storage to use BD–Live features, after Sony upgrades the BDP–S350 to be a Profile 2.0 player.
