More Questions from Memory and Storage

• A CD player is an example of a device that has random access capability.
• A term often used commercially to refer to read/write memory is sequential-access memory.
• If a memory design allows a storage location to be accessed without first sequencing through other locations, it is called Random Access Memory.
• Flash memories are frequently used in place of floppy or small-capacity hard disk drives in portable computers.
• EEPROM and Flash memory are electrically erasable.
• The floating-gate MOSFET is the actual storage element for EEPROMs. An electron charge will remain on the floating gate for more than 10 years unless drained off electrically.
• More than one bit of data can occupy each memory cell.
• PROMs are basically the same as mask ROMs, once they have been programmed.
• Once a PROM is programmed it can be changed by applying a small electrical charge.
• DRAM chips can be combined for larger capacity and word sizes using the same methods as for other memory types.
