*Need help on 1 h, i, j. Thank you !!

1. Given: 2MB of physical memory. Formed using 256 KB chips. A CPU with a 24 bit address bus and an 8 bit data bus.

h. Suppose I replaced the 256K RAM chip at the highest address, with a 256K EPROM chip, what would the address be of the lowest byte in the EPROM?

i. If I upgraded the RAM chips to 512K versions, how many bits would be required to select a specific chip?

j. How many 512K chips would be needed to fill the 24 bit address space?
