In a register stack, data moves up but not down.

More Questions from Memory and Storage

• Static memory will maintain storage even if power is removed.
• The main advantage of bipolar (TTL) memories over MOS memories is speed.
• Cache memory is used in high-speed systems.
• Information stored in an EPROM can be erased by prolonged exposure to ultraviolet light.
• EEPROMS can be electrically erased and reused.
• An optical disk is an example of magnetic storage.
• One of the advantages of DRAMs is their ability to store data without needing periodic refreshment of the memory contents.
• The EPROM is strictly a MOS device.
• The highest-speed magnetic storage is achieved by using a floppy disk.
• Due to their ability to be easily erased and reused, magnetic memory devices are widely used for RAM.
