How many lines of address bus used for memory of 2048 bytes, Computer Engineering

Assignment Help:

How many lines of address bus must be used to access 2048 bytes of memory when available RAM chips 128 × 8. How many lines of these will be common to each chip?

Ans. AS chips available here of 128 x 8 in size. Thuis means that total 128(2⁷) locations are here and all locations can store 8 bits. Hence the total number of address lines required to access
128 locations is 7. Since seven address lines can address 27 locations so all seven lines are common to all chips.
