``A method of memory management for a primary memory created from a non-volatile, long-term storage medium, in particular flash memory, which enables direct manipulation of data segments stored therein.``

``The method comprises the minimum steps of dividing the primary memory into equal size blocks, each block being the smallest amount of data which can be read from or written to memory in a single read or write operation. A cache memory the size of at least one of the read/write blocks is then coupled to the primary memory and provides temporary storage space for data being written to and read from primary memory.

For the above implementation `` data storage and retrieval is optimized, so as to decrease system overhead and thereby increase data throughput, system stability and fault tolerance.``

The above is not the only attributiable condition...you also have to have a data segment structure that eliminates overhead also.....e.Digital package is patented.
