Question

Match List - I with List - II.

List - I	List - II
A. ROM B. EPROM C. EEPROM D. SRAM	I. Volatile, Fast, Expensive II. UV erasable III. Electrically erasable IV. Non-Volatile, permanent data

• A. A-I, B-II, C-III, D-IV
• B. A-I, B-III, C-II, D-IV
• C. A-IV, B-II, C-III, D-I
• D. A-IV, B-III, C-II, D-I

Hint:

Memory types:
• ROM \(\rightarrow\) Permanent storage
• EPROM \(\rightarrow\) UV erasable
• EEPROM \(\rightarrow\) Electrically erasable
• SRAM \(\rightarrow\) Fast volatile memory

Answer 1

The Correct Option is C

Concept: Different semiconductor memories possess different properties regarding:
• Speed
• Volatility
• Erasability
• Cost

Step 1: Match ROM. ROM stands for: \[ \text{Read Only Memory} \] Properties:
• Non-volatile
• Stores permanent data Hence: \[ A \rightarrow IV \]

Step 2: Match EPROM. EPROM stands for: \[ \text{Erasable Programmable ROM} \] It is erased using: \[ \text{Ultraviolet light} \] Therefore: \[ B \rightarrow II \]

Step 3: Match EEPROM. EEPROM stands for: \[ \text{Electrically Erasable Programmable ROM} \] Thus: \[ C \rightarrow III \]

Step 4: Match SRAM. SRAM means: \[ \text{Static RAM} \] Properties:
• Volatile
• Very fast
• Expensive Hence: \[ D \rightarrow I \]

Step 5: Write complete matching. Therefore: \[ A-IV,\ B-II,\ C-III,\ D-I \]

Step 6: Write the final answer. Hence the correct option is: \[ \boxed{(C)\ A-IV,\ B-II,\ C-III,\ D-I} \]
