8-bit Microprocessor

|
20-bit address bus
|
|
|
16-bit data bus
|
|
|
17-address line
|
Detailed explanation-1: -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.
Detailed explanation-2: -Representation. A processor with 128-bit byte addressing could directly address up to 2128 (over 3.40×1038) bytes, which would greatly exceed the total data captured, created, or replicated on Earth as of 2018, which has been estimated to be around 33 zettabytes (over 274 bytes).
Detailed explanation-3: -A memory system of size 16 k bytes is required to be designed using memory chips which have 12 address lines and 4 data lines each.
Detailed explanation-4: -Kilobit or kilobyte? If it is 128 kilobyte, the 8 data lines will be enough for transferring 1 byte. 1024 bytes requires 10 bits of address, and 128 locations 7 bits, so a 17 bit address bus would be needed, assuming a separate address bus. You would also need some control lines for read/write and so on.
