Semiconductor Memory MCQs : This section focuses on the "Semiconductor Memory". These Multiple Choice Questions (MCQs) should be practiced to improve the Semiconductor Memory skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
How many storage locations are available when a memory device has twelve address lines?
A computerized self-diagnostic for a ROM test uses:
A. the check-sum method
B. a ROM listing
C. ROM comparisons
D. a checkerboard test
Which of the following memories uses a MOSFET and a capacitor as its memory cell?
The access time (tacc) of a memory IC is governed by the IC's:
A. internal address buffer
B. internal address decoder
D. internal address decoder and volatility
Select the best description of the fusible-link PROM.
A. user programmable, one-time programmable
B. manufacturer programmable, one-time programmable
C. user programmable, reprogrammable
D. manufacturer programmable, reprogrammable
A nonvolatile type of memory that can be programmed and erased in sectors, rather than one byte at a time is:
A. flash memory
What is the principal advantage of using address multiplexing with DRAM memory?
A. reduced memory access time
B. reduced requirement for constant refreshing of the memory contents
C. reduced pin count and decrease in package size
D. no requirement for a chip-select input line, thereby reducing the pin count
Which of the following best describes nonvolatile memory?

C. magnetic memory
D. nonmagnetic memory
Which of the following best describes static memory devices?
A. memory devices that are magnetic in nature and do not require constant refreshing
B. semiconductor memory devices in which stored data is retained as long as power is applied
C. memory devices that are magnetic in nature and require constant refreshing
D. semiconductor memory devices in which stored data will not be retained with the power applied unless constantly refreshed
Memory that loses its contents when power is lost is:
Advantage(s) of an EEPROM over an EPROM is (are):
A. the EPROM can be erased with ultraviolet light in much less time than an EEPROM
B. the EEPROM can be erased and reprogrammed without removal from the circuit
C. the EEPROM has the ability to erase and reprogram individual words

D. trc and twc
Select the best description of read-only memory (ROM).
A. nonvolatile, used to store information that changes during system operation
B. nonvolatile, used to store information that does not change during system operation
C. volatile, used to store information that changes during system operation
D. volatile, used to store information that does not change during system operation
