How many memory locations can be accessed by using 8 bit address lines?
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 addresses can a 8 line address bus address?
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 memory locations can be addressed using 12 bit address lines?
A 64-bit (8 byte) wide memory could address 32768 bytes. A row and column addressed 64 bit wide DDR DRAM with 8 byte bursts and 12 address bits could address 4 Gigabytes (8 bits of “address” for the block size, plus 12 for the row and 12 for the column gives 32 bits.)

How many data lines are there in a 16 * 2 alphanumeric LCD?
eight data lines
How many address bits are required for a 4096 bit memory Organised as a 512 * 8 memory?
Answer: The memory address space is 128 MB, which means 227. However, each word is 8 (23) bytes, which means that you have 224 words. This means you need log2 224 or 24 bits, to address each word.
How many address lines a memory chip of 128k capacity will have?
for 128kb, you need 10 bits for each k and then 7 more bits. and thats for the address and if has 8 lines means its 128 kBytes. if you use the 8 lines as 1 byte each. now, the input lines are 8 of course.
How do I know my memory size?
Check your total RAM capacity
- Click on the Windows Start menu and type in System Information.
- A list of search results pops up, among which is the System Information utility. Click on it.
- Scroll down to Installed Physical Memory (RAM) and see how much memory is installed on your computer.
What will be memory capacity of RAM if it has 10 bit address lines?
Notice that with ten address lines you can address the magic number of 1024 memory locations, and this is the closest you can get to 1000 using this system – hence 1K = 1024.
How much RAM do I need for 128 bit?
That aside, a processor using 128-bit memory addressing could address 3.40 × 10^38 bytes of RAM.
How much RAM do I need for 64-bit?
Modern 64-bit processors such as designs from ARM, Intel or AMD are typically limited to supporting fewer than 64 bits for RAM addresses. They commonly implement from 40 to 52 physical address bits (supporting from 1 TB to 4 PB of RAM).
What is the highest capacity of RAM?
If a computer is running a 32-bit processor, the maximum amount of RAM it can address is 4GB. Computers running 64-bit processors can hypothetically handle hundreds of terabytes of RAM.
