If the memory chip size is 256*1 bits, then the number of chips required to make up 1 K bytes of memory is
- A. 32
- B. 24
- C. 12
- D. 8
Answer: A. 32
Explanation: 1 K byte of memory = 1024 bytes = 1024 * 8 bits. The size of one memory chip is 256 bits (256 * 1). The number of chips required is total capacity divided by single chip capacity: (1024 * 8) / 256 = 4 * 8 = 32 chips.
