3
4
Solution
✅ Finding the Memory Size:
The last memory location "FFFF" is a hexadecimal number.
Each hexadecimal digit represents 4 bits, so:
- "FFFF" is a 4-digit hexadecimal number, meaning it represents 16 bits or 2 bytes.
- "FFFF" in decimal is equivalent to 65535.
- Therefore, the total memory size is 65536 bytes or 64 KB.
✅ Final Answer:
The memory size is: 64 KB

Solution
Stored-program concept = microprocessor
Access time = $45\text{ ns}$, gap = $5\text{ ns}$
Bandwidth = ?
1
