How many 128 × 8 bit RAMs are required to design 32 K × 32 bit RAM?
- A.
512
- B.
1024
- C.
128
- D.
32
Attempted by 233 students.
Show answer & explanation
Correct answer: B
Calculate total memory capacity required: 32 K × 32 bits = (32 × 1024) × 32 = 1,048,576 bits. Calculate capacity of one chip: 128 × 8 = 1,024 bits. Divide total capacity by chip capacity: 1,048,576 / 1,024 = 1024 chips.
