    Suppose that a 256M * 128 Memory built using 1024 K *32 RAM Chips and memory is word addressable.

    a. How many RAM Chips are necessary?

    (256*10^6)/(1024*10^3)*(128/32)=1000

    b. How many RAM Chips are there per memory word?

    128/32=4

    c. How many address bits are needed for each RAM Chip?

    ln(1024*10^3)/ln(2)=~20

    d. How many banks will this memory have?

    maximum addressable word size not clear
    if it is 32 then 128/32=4


    e. How many address bits are needed for all memory?


    ln(256*10^6)/ln(2)=~28
