Examples of magnetic memories are tapes, floppy disks, hard drives and ferroelectricRAMs. Examples of optical memories are CD-ROMs, rewrittable CDs. Electronic memory is used extensively in computer equipment since it is the fastest available. For applications where speed is less important, magnetic and optical technologies are often used. All electronic memory today can be in separate IC format, module format, or can be part of an IC as a macrofunction or?cell?e In the table below is an overview of some electronic memory. The flip-flop A flip-flop is basically a bi-state circuit in which either a 0 or 1 state
