Question

If the memory chip size is 1024x4 bits, how many chips required for making 2k of memory

Answer 1

Answer:

You need 4 Chips

Explanation:

One Byte is 8 bits , so two 1024 x 4 chips would make 1KB memory

Double that to get 2KB

Answer 2

Answer: 4 chips are required.

Explanation:

GIVEN:

• Size of memory chip = 1024 x 4 bits.
• Given memory = 2 k

To calculate:

• Number of chips required for 2k of memory.

Calculations:

• 1 k memory = 1024bytes
• 2k = 1024 x 2 bytes

• 1 byte = 8 bits.
• 1024 x 2bytes = 1024 x 2 x 8 bits.

• 1024 x 4  = 1 memory chip.
• 1024 x 2 x 8 bits = (1024 x 2 x 8 / 1024 x 4)

                                    = 4 memory chips.

4 chips are required for making 2k memory.
