Memory Technology of Embedded System MCQ Quiz – Objective Question with Answer for Memory Technology of Embedded System

1. Which is the most basic non-volatile memory?

A. Flash memory

Answer: D

The basic non-volatile memory is ROM or masks ROM, and the content of ROM is fixed in the chip which is useful in firmware programs for booting up the system.


2. Who invented flash memory?

A. Dr.Fujio Masuoka
B. John Ellis
C. Josh Fisher
D. John Ruttenberg

Answer: A

Flash memory is invented by Dr. Fujio Masuoka at Toshiba in the 1980s as is non-volatile memory.


3. Which of the following is serial access memory?
B. Flash memory
C. Shifters

Answer: C

The memory arrays are divided into three which are random access memory, serial access memory, and content address memory. Serial access memory is divided into two, these are shifters and queues.

4. Which is the early form of non-volatile memory?

A. magnetic core memory
B. ferrimagnetic memory
C. anti-magnetic memory
D. anti-ferromagnetic

Answer: A
The early form of non-volatile memory is known as magnetic core memory in which the ferromagnetic ring was magnetized to store data.


5. Which of the following memories has more speed in accessing data?


Answer: A

SRAM has more speed than DRAM because it has 4 to 6 transistors arranged as flip-flop logic gates, that is it can be flipped from one binary state to another but DRAM has a small capacitor as its storage element.


6. In which memory, the signals are multiplexed?


Answer: A

The signals in the address bus are multiplexed with DRAM non-multiplexed with SRAM.


7. How many main signals are used with memory chips?

A. 2
B. 4
C. 6
D. 8

Answer: B

The main signals associated with memory chips are four. These are the signals associated with the address bus, data bus, chip select signals, and control signals for read and write operations.


8. What is the purpose of the address bus?

A. to provide data to and from the chip
B. to select a specified chip
C. to select a location within the memory chip
D. to select a read/write cycle

Answer: C

The address bus is used to choose a particular location in the memory chip. The data bus is used to provide data to and from the chip. Chip select signals are used to select a particular chip within the memory.


9. Which are the two main types of processors connected to the motherboard?

A. sockets and slots
B. sockets and pins
C. slots and pins
D. pins and ports

Answer: A

The type of processor which connects to a socket on the bottom surface of the chip that connects to the motherboard by Zero Insertion Force Socket. Intel 486 is an example of this type of connection. The processor slot is one that is soldered into a card, which connects to a motherboard by a slot. An example of a slot connection is Pentium 3.


10. Which of the following has programmable hardware?

A. microcontroller
B. microprocessor
C. coprocessor

Answer: D

Field programmable gate arrays are a type of multi-core architecture whose hardware function can be programmed by using hardware design tools.
