[SI-LIST] Stitching CAPs between DDR VDD and VTT Power Rails

Hello,

The DDR termination power rail should have sinking capability. Normally
VTT is generated from the VDD and in switching regulator based solutions
the upper FET provides the sinking path from VTT to VDD.

With the upper condition met, How does an array of stitching capacitors
(several 0.1uf ceramic caps and few larger tantalum caps) between the
VDD and VTT helps?

Thanking all in advance,
Regards,
Harjeet.
