How many memory locations can be accessed?
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.
How many different memory locations can be accessed using 12 bits?
4096 locations
Each memory location is one byte, while the address is 12-bit, with the capability to address up to 4096 locations.
How many memory locations can be accessed using 8 address lines?
How many memory locations are identified by a processor with 8 bit address bus at a time? – Quora. The facile answer is “256” because 8 bits can only have 256 different values.
How many locations can a memory chip having 14 address pins and 4 data pins address?
So only 4 addresses can be assigned using 2 bit address bus. So for 14 bit bus, addresses = 2 ^ 14 = 16 X 1024 addresses. Answer: It is 2^14 memory lacations can be addressed by a microprocessor with 14 address lines.
How many memory locations can be accessed if we are having an N bit address bus?
If there are just 2 bits in the address, then there can only be 4 addresses, viz. So, if we have n bits to store an Address (n-bits in Address Register) or n-wires to transfer the address (Address bus of size 10), then we can have RAM of 2n addresses.
What is the maximum number of memory locations that can be addressed by a chip with 16 address pins?
Using 16 bits, you can write 65536 addresses (from 0 to 65535, that’s 65536 different addresses), and address 65536 bytes. 65536 bytes is 64kB. In computer science, b is bit, B is byte. The byte is the smallest amount of memory you can address.
How many address lines are needed for 2 MB?
Answer: It requires 21 address lines to address two megabytes of memory.
How much memory can a 32-bit address?
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. The actual limit is often less around 3.5 GB since part of the register is used to store other temporary values besides memory addresses.
Can a computer access any address in memory?
The computer can access any address in memory at any time (hence the name “random access memory”). It can also group bytes together as it needs to to form larger variables, arrays, and structures.
Why are memory addresses called random access memory?
Memory addresses act just like the indexes of a normal array. The computer can access any address in memory at any time (hence the name “random access memory”). It can also group bytes together as it needs to to form larger variables, arrays, and structures.
Which is the address of the first byte in memory?
Memory can be thought of simply as an array of bytes. In this array, every memory location has its own address — the address of the first byte is 0, followed by 1, 2, 3, and so on. Memory addresses act just like the indexes of a normal array. The computer can access any address in memory at any time (hence the name “random access memory”).
How does the address of a memory array work?
In this array, every memory location has its own address — the address of the first byte is 0, followed by 1, 2, 3, and so on. Memory addresses act just like the indexes of a normal array. The computer can access any address in memory at any time (hence the name “random access memory”).
