216 = 65536
for 16 MB memory has 24 address lines
It takes 23 address lines to address 8 mb of memory.
168
2^14 memory locations. In general for n-bit address bus, its 2^n
You can address 214 or 16384 different locations with 14 address lines.
depends on the depth of memory, N address lines can map 2 Power N locations.
32 bit address line can access 4GB of memory. As 2^10 -> 1KB; 2^20 -> 2MB; 2^30 -> 1GB and so on.... 32 bit gives (2^30) * (2^2) = 1GB * 4 = 4GB;
The Intel 8088 microprocessor has 20 address lines. This allows it to address up to 1 MB (2^20 bytes) of memory. The address lines are labeled A0 to A19, enabling the microprocessor to access a wide range of memory locations.
Firstly we need to convert Mb's into bits i.e 1Mb=1024x1024 = 210x210 =220 That means there are 220 memory locations and we will need 20 address lines.
A 2K X 8 memory requires 11 address lines and 8 data lines
The PIC16F877A microcontroller has 13 address lines, which allows it to address 8K words of program memory. This enables it to access a range of memory locations for storing instructions. Additionally, it has 368 bytes of data RAM and 256 bytes of Electrically Erasable Programmable Read-Only Memory (EEPROM) for data storage.
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.
