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

Trueeeèèèè...........

Answer 2

FALSE.

Explanation:

• A data bus is a system which consist 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

• A 64bit memory address does not need a data bus of64 bit
• In fact it need a much lesser a data bus of 6 width,
• As 2 raised to power 6 is equal to 64 .
• A data bus of 64 bit will be able to address 2 raised to the power of 64 bits ,that's a very huge amount of data.
