Question

A physical memory has a word-width of 64 bits, this mandates the logical memory map to adopt a data-bus of width 64 bits.
True
False

Answer 1

the answer is true not false

Answer 2

True

Explanation:

• A data bus is a system which consists of connected wires and is used for transportation of data within the system.
• The number of lines in the group is called the width of data bus.
• Each line being capable of transporting one bit of information.
• To transfer 64 bits, we need 64 lines.
• One line carries one bit of data.
• If we have less lines, we will miss the information present in remaining length of the word.

Hence, 64 bits memory address needs a data bus of 64 bits.
