Question

A computer system has 16-bit wide address/data bus that uses RAM chips of \(4K \times 8\)-bit capacity. The number of RAM chips needed to provide a memory capacity of 64 Kbytes memory is

• A. 32
• B. 16
• C. 64
• D. 8

Hint:

Convert KB to bytes and divide by chip capacity to find required number of chips.

Answer 1

The Correct Option is B

Step 1: Total memory required = 64 KB = 64 × 1024 = 65536 bytes
Step 2: Each RAM chip has capacity = \(4K = 4 \times 1024 = 4096\) bytes
Step 3: Number of chips required = \(65536 \div 4096 = 16\)
