DDR3 bulk and decoupling capacitors

I’m just wondering where you got the info for how much bulk and decoupling capacitors to use in your DDR3 designs? I cannot find any reference on how much caps the circuit should have in IMX6 data sheet nor in Micron’s data sheet. Though I can see that you use in 4X10 220nF decoupling capacitors in NVCC_DDR3 and 6 22uF bulk capacitors in 1V5_DDR.

I know that using more capacitors doesn’t hurt the functionality but it hurts your wallet if there is too much capacitors.

Tingo, we try to follow iMX6 reference designs and iMX6 Design guide (e.g. just search for “decoupling”). It doesn’t say exactly how many capacitors to you use for DDR3, but it may help you.
