How Many Memory Locations Can Be Addressed With Address Bus Of 16 Bits? - Fixanswer

In many older computers, the address bus was 16 bits wide (a = 16). This meant

that there were 16 wires

. Such microprocessors could address up to 2
¹⁶
= 65536 memory locations. By increasing the width of the address bus, more memory locations can be directly addressed.

How many memory locations can be addressed in a computer system with an 8-bit data bus and a 16-bit address bus?

In 8085 microprocessor, Address bus is of 16 bits (A0-A15) and can transfer maximum 16 bit address and hence can address

65,536 different memory locations

. This bus is multiplexed with 8 bit data bus. So, the most significant bits (MSB) of address goes through Address bus and LSB goes through multiplexed data bus.

What will be the size of memory address space for a 16-bit data and 20-bit address bus?

For instance, many 8-bit processors, such as the MOS Technology 6502, supported 16-bit addresses— if not, they would have been limited to a mere

256 bytes

of memory addressing. The 16-bit Intel 8088 and Intel 8086 supported 20-bit addressing via segmentation, allowing them to access 1 MiB rather than 64 KiB of memory.

How much memory is addressable on a 12 bit address bus?

Address bus size Addressable memory (bytes)	9 512	10 1K ^*	11 2K	12 4K

How many memory locations can a processor address?

The microprocessor can access

216=65536 memory addresses

, regardless of the size of data held at each memory address. If each memory address holds one byte (8 bits) of data then the total memory size that can be addressed directly is 216 bytes, which is 26 KiB=64 KiB.

Which is the only register that can give memory address?

In a computer, the

memory address register (MAR)

is the CPU register that either stores the memory address from which data will be fetched to the CPU, or the address to which data will be sent and stored.

How do I find my memory address?

Take your 16-bit segment and offset addresses and break them into pairs. …
Add the two 20-bit addresses together in binary form to get the hexadecimal address of the memory.

How many gigabytes of memory space can a 20-bit address bus address?

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). See binary values.

What is the size of address bus to access 2gb of memory?

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).

How many messages can 12 bits send?

A 12-bit digital value can represent

4096 (2
¹²
) different numbers

. A 16-bit digital value can represent 65536 (2
¹⁶
) different numbers. It might occur to you at this point that a digital input could be thought of as a 1-bit analog to digital converter. Low voltages give a 0 and high voltages give a 1.

What is the 12-bit integer limit?

Number of Bits Maximum States	8 256	12 4096 (4 K)	16 65,536 (64 K)	20 1,048,576 (1 M)

What is the maximum memory address?

Are 4 bits enough to store 8 directions?

Four bits are not enough to store the eight directions

. … Eight bits are needed for the new version of the game.

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.

How many bits are required in the address for memory of 32 GB in size?

So you will need, at least

25 bits

to address a single byte in that memory scheme.
