- The basic external memory model (cf., e.g., [27]) can be viewed as a refinement of the RAM model where memory is divided into internal memory, capable of storing up to M data items, and external memory of unbounded size. Data present in internal memory can be accessed quickly (as in the RAM model). Data present in external memory can only be accessed by an operation called Input/Output communication (I/O, for short) that moves a contiguous block of B data items between internal and external memory. Initially, the N input items are stored in external memory. One typically assumes that M < N and 1 6 B 6 M/2.
