  2. Optical disks

  3. Semiconductor chips

  4. Magnetic tapes


Correct Option: C
Explanation:

Solid state memories utilize semiconductor chips as their primary storage medium, which allow for fast data access and storage.

Which type of solid state memory is known for its non-volatile nature and ability to retain data even when power is turned off?

  1. DRAM

  2. SRAM

  3. EEPROM

  4. Flash memory


Correct Option: D
Explanation:

Flash memory is a type of non-volatile solid state memory that can retain data even when power is turned off, making it suitable for long-term storage.

What is the primary advantage of DRAM (Dynamic Random Access Memory) over SRAM (Static Random Access Memory)?

  1. Lower power consumption

  2. Higher storage capacity

  3. Faster access speed

  4. Lower cost


Correct Option: B
Explanation:

DRAM offers higher storage capacity compared to SRAM due to its ability to store more data in a single memory cell.

In the context of solid state memories, what does the term 'cell' refer to?

  1. A single memory location

  2. A group of memory locations

  3. A storage unit for data

  4. A semiconductor material


Correct Option: A
Explanation:

In solid state memories, a cell refers to a single memory location that can store a bit of data.

  3. NAND flash memory is used in USB flash drives, while NOR flash memory is used in solid state drives.

  4. NAND flash memory is more expensive than NOR flash memory.


Correct Option: B
Explanation:

NAND flash memory offers higher storage capacity compared to NOR flash memory, while NOR flash memory provides faster access speed.

What is the primary function of a memory controller in a solid state memory system?

  1. To manage data transfer between the memory and the processor

  2. To store data permanently

  3. To refresh the memory cells periodically

  4. To decode memory addresses


Correct Option: A
Explanation:

The memory controller is responsible for managing data transfer between the solid state memory and the processor, ensuring efficient and reliable data access.

Which type of solid state memory is commonly used in embedded systems and microcontrollers?

What is the term used to describe the process of periodically refreshing the memory cells in DRAM to prevent data loss?

  1. Write leveling

  2. Wear leveling

  3. Memory scrubbing

  4. Refresh cycle


Correct Option: D
Explanation:

DRAM requires periodic refreshing of its memory cells to prevent data loss. This process is known as the refresh cycle.

Which type of solid state memory is known for its ability to be erased and reprogrammed multiple times?

  1. DRAM

  2. SRAM

  3. EEPROM

  4. Flash memory


Correct Option: C
Explanation:

EEPROM (Electrically Erasable Programmable Read-Only Memory) allows for multiple erasing and reprogramming cycles, making it suitable for applications where data needs to be updated frequently.

What is the main advantage of using solid state memories over traditional magnetic storage devices?

  1. Higher storage capacity
