Your system has an IGP  - integrated graphics processor, with no
memory chips. Thus no memory clk is used nor set.

nvidia-settings reports the frequency of your system memory.
In some vbioses the memory clk for IGPs is set to 0 just to explicitly
confirm the above statement.

On nva[3|5|8|f] systems the get_clock() function does not always the
clocks correctly (looking at your shader frequency)
