00 to 0F represents 16 addresses Binary representation is 1111 therefore you need 4 address lines to connect to all addresses
In the 2k*16 , the 11 address lines are required and the 16 input-output lines are required..
How many no of address lines required in 1MB memory 11,16,22 or 24 u haven't specified correct options! 20 address lines will be required because 1 MB is 1024 KB that is 1024*1024 Byte which is equivalent to (2^10)^2 bytes if ur memory is Byte addressable then address lines required will be 20.
A 2K X 8 memory requires 11 address lines and 8 data lines
17 address lines and 8 data lines. 2^17=128k
2kb=2*1024=2048 2^11=2048 therefore 11 address lines are required
The number of address lines needed to access N-KB is given by log2N Then the number of address lines needed to access 256KB of main memory will be log2256000=18 address lines.
10. 210 = 1024.
It takes 23 address lines to address 8 mb of memory.
There are 24 address lines required for 16 mb. That covers 12 mb. The next step down is 23 address lines, which is 8 mb. The 8085 and 8086/8088 cannot address 12 mb. Only the 80286 and higher can.
Microprocessor has 16 address lines and microcontroller has 20 address lines
You need 12 address lines to access 4K of memory. 212 = 4096. log2 (4096) = 12.
ANSWER There are 2128 combinations of addresses. This is about 3.4 x 1038 locations. Assuming each address holds a 32-bit word, that's 1.2 x 1039 bytes. That's a LOT of memory.
