The following RAM chips are specified by the number of words times the number of bits per word. For each, specify:
a. The number of address lines needed for each memory chip
b. The number of data lines needed for each memory chip
c. The number of bytes that can be stored in each memory chip (note that there are 8 bits/byte)
128 KB words x 8 bits/word
512 KB words x 16 bits/word
512 MB words x 32 bits/word
8 GB words x 64 bits/word
