    There total capacity of RAM is 4096 bits.

    Word Size = 16 bits

    Total Number of words in RAM = 4096/16

    Total Number of words in RAM = 256 locations

    Now compute the number of addresses.

    No. of addresses = log₂ (256)

    = log₁₀ (256) / log₁₀ (2)

    No. of addresses = 8 address lines

    Total 8 address lines required to address 256 locations RAM of size 16 bit each location.

    Explanation:

    There we are unable to calculate log base 2. There is a formula to calculate this as

    log₂ (x) = log₁₀ (x) / log₁₀ (2)
