CMOS power dissipation is a direct function of clock frequency.
*But*, you will find that at DC (which is where the device
operates when in sleep mode) there are huge differences in the
static Icc between different grades of SRAMs -- from the same
manufacturer and P/N.
But cache RAM
is power hungry and has little practical chance
of being converted to BBSRAM
Most are not, few if any of mine are not. NOTE: many of those rams
are CMOS and at high cycle rates the power needed is impressive but
in standby and low cycle rates the power drops significantly! Often
they are spec'd at they fastest cycle time for power use as thats how
PCs used them.
