Digital Electronics-Memory and Storage
121. Information stored in an EPROM can be erased by prolonged exposure to ultraviolet light.
- TRUE
- FALSE
122. A CD player is an example of a device that has random access capability.
- TRUE
- FALSE
123. The most widespread application of ROMs is in the storage of data and program codes that must be available on power-down in the microprocessor-based systems. These data and program codes are called firmware because they are firmly stored in hardware.
- TRUE
- FALSE
124. One of the advantages of DRAMs is their ability to store data without needing periodic refreshment of the memory contents.
- TRUE
- FALSE
125. A typical RAM will write (store data internally) whenever the Chip Select line is active and the Write Enable line is inactive.
- TRUE
- FALSE
126. When two or more devices try to send their own digital levels to a shared data bus at the same time, bus contention will take place.
- TRUE
- FALSE
127. The main advantage of bipolar (TTL) memories over MOS memories is speed.
- TRUE
- FALSE
128. Testing and troubleshooting the decoding logic will not reveal problems with the memory chips and their connections to the CPU busses.
- TRUE
- FALSE
129. Once a PROM is programmed it can be changed by applying a small electrical charge.
- TRUE
- FALSE
