Question

A memory map to lowest address of 8k by 8 RAM is 1000H. What is highest address?

• A. 8192 H
• B. 2FFF H
• C. 7FFF H
• D. 3000 H

Hint:

Highest address = Start + Size − 1.

Answer 1

The Correct Option is B

Concept: Memory addressing depends on size and starting address.

Step 1: Convert size \[ 8K = 8 \times 1024 = 8192\ \text{bytes} \]

Step 2: Starting address \[ \text{Start} = 1000_H \]

Step 3: Ending address formula \[ \text{End} = \text{Start} + (\text{Size} - 1) \]

Step 4: Calculation \[ 1000_H + (2000_H - 1) = 1000_H + 1FFF_H = 2FFF_H \]

Step 5: Conclusion \[ \boxed{2FFF_H} \]

Final Answer: \[ \boxed{(B)} \]
