What will be the size of the memory if its address consists of 22 bits and memory is 2 byte addressable?

Find the size of the memory if its address consists of 22 bits. Assume the memory is 2-byte addressable. If the given address consists of ‘k’ bits, then 2k locations are possible. Size of memory = 2k x Size of one location.

How much memory can be accessed with a 32-bit address?

The CPU register stores memory addresses, which is how the processor accesses data from RAM. One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4 GB (4,294,967,296 bytes) of RAM.

How many byte addressable addresses can a 32-bit processor support that has 20 address lines on the address bus between it and main memory explain?

For example, an 8-bit-byte-addressable machine with a 20-bit address bus (e.g. Intel 8086) can address 220 (1,048,576) memory locations, or one MiB of memory, while a 32-bit bus (e.g. Intel 80386) addresses 232 (4,294,967,296) locations, or a 4 GiB address space.

What will be the size of memory if address bus size is 22 bits?

13.6 Memory addressing size

Address bus size	Addressable memory (bytes)
21	2M
22	4M
23	8M
24	16M

How many bits are required in address for memory of 32gb in size consider the given memory is 2 byte addressable?

As far as I see 2^15 is 32768 which is 32 MB so the answer could be 15 bits.

How many bits are required in the address for memory having size of 32 GB if the memory is word addressable the word size is 8 bytes?

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

What is a 32-bit address?

A 32-bit address is the address of a single byte. Thirty-two wires of the bus contain an address (there are many more bus wires for timing and control). Sometimes people talk about addresses like 0x2000, which looks like a pattern of just 16 bits. But this is just an abbreviation for the full 32-bit address.

What does 32 bit word size mean?

“Word size” refers to the number of bits processed by a computer’s CPU in one go (these days, typically 32 bits or 64 bits). Data bus size, instruction size, address size are usually multiples of the word size.

What is a 20 bit address bus?

The number of lines (wires) in the address bus determines the maximum amount of RAM that can be directly accessed by the CPU as each line carries one bit of the address. In 1981, the IBM PC had a limit of one megabyte of RAM because its address bus had 20 lines, and 20 bits represents the number 1,048,576 in binary.
