In a memory hierarchy various storage devices are structured into various levels. By convention, information at storage level i may be accessed and stored in less time than information at storage level i+1. Since a smaller access time generally implies a greater cost per bit of storage, storage level i will generally be smaller than storage level i+1. An example of such an arrangement with four levels is a system with core, drum, disc and tape memory devices.
