How many 128×8 bit RAMs are required to design 32K×32 bit RAM?
Correct Answer: B
Question 18 Explanation:
Step-1: RAM size required is 32Kx32 bits
= 32x1024x32 bits. [Note: 1k=1024 bytes]
= 32x1024x32 bits. [Note: 1k=1024 bytes]
Step-2: Given RAM chip capacity is 128×8 bits
Step-3: Required size/Given size
=(32*1024*32) / (128*8)
=1024
512
1024
