How many bits would you need to address a memory if the memory is byte addressable?

Therefore 32 bits are required to uniquely address each 32-bit word. Therefore 34 bits are required to uniquely address each byte.

How can we calculate the size of memory if there are 32 address lines and 16 data word lines?

32 Address lines means 2^32 possible addresses, and a data bus 16 bits wide accommodates 2 bytes, so that means that in terms of bytes, the memory space is 2^33, or 8,589,934,592 bytes. This is otherwise known as 8GB.

What is the amount of memory that can be addressed by this computer if the processor has a data bus of 24 bits and an address bus of 32 bits?

Address Bus Size The size of the address bus determines how much memory the CPU can address directly. For example, a 20-bit address bus can access up to one megabyte (1MB); 24 bits reaches 16MB, and 32 bits can handle four gigabytes (GB).

What is 4M in memory?

Memory is often referred to using the notation length X width (L X W). For example, 4M X 8 means the memory is 4M long (it has 4M = 2^2 X 2^20 = 2^22 items) and each item is 8 bits wide (which means that each item is a byte).

How many bits would you need to address a 4M 32 memory if the memory is word addressable?

4M X 8 bit memory requires 21 bit addresses if it is word-addressable and word size is 16 bits. 4M X 8 bit memory requires 20 bit addresses if it is word-addressable and word size is 32 bits.

Why does 32-bit only support 4gb RAM?

Because each byte of memory has to have an address. In a 32-bit operating system, an address is 32 bits long; thus, there are 2^32 possible addresses, which means there are 2^32 bytes = 4 GB.

How many address lines 32gb memory belongs to?

a system with a 32-bit address bus can address 232 (4,294,967,296) memory locations. Total 8 values. So using ABC , you can access any of those eight values, i.e., you can reach any of those memory addresses. So, TL;DR, the simple relationship is, with n number of lines, we can represent 2n number of addresses.

How many memory locations can be addressed through the address bus?

An address bus is measured by the amount of memory a system can retrieve. A system with a 32-bit address bus can address 4 gigabytes of memory space. Newer computers using a 64-bit address bus with a supporting operating system can address 16 exbibytes of memory locations, which is virtually unlimited.

What is the minimum size of the address bus to access all bytes in a 4gb RAM?

Likewise, you need 20 bits to address every byte in a megabyte, and 30 bits to address every byte in a gigabyte. 232 = 4294967296, which is the number of bytes in 4 gigabytes, so you need a 32 bit address for 4 GB of memory.
