Designing a 64k 8 Bit Word Memory Unit with 4096x4 Chips

[mathrocks]

Hi, how do you go about figuring out how many memory chips are needed to design a memory unit that contains 64k 8 bit words and each memory chip is 4096x4?

Thanks

Well, each of your 4k x 4 chips provides 4k addresses. You need 64k addresses, so you're going to need 16 of those chips just to get enough addresses. Futhermore, each chip only provides 4 bits per address, and you need 8 bits per address, so you'll need two chips per address. Thus, you'll need 16 * 2 = 32 chips.

for asking! To determine the number of memory chips needed for this design, we first need to calculate the total number of bits required for a memory unit with 64k 8 bit words. This can be done by multiplying 64k (64,000) by 8, which gives us 512k (512,000) bits in total.

Next, we need to determine the capacity of each memory chip. In this case, each chip has a capacity of 4096x4, which means it can store 4096 words with 4 bits each, giving us a total of 16,384 bits per chip.

To find the number of chips needed, we can divide the total number of bits required (512k) by the capacity of each chip (16,384). This gives us a total of 32 chips needed to design a memory unit with 64k 8 bit words using 4096x4 chips.

I hope this helps! Let me know if you have any further questions.
