DDR Termination Regulators
What are DDR Termination Regulators?
DDR termination regulators are an essential component to regulate power through DDR transmission lines. DDR Termination Regulators achieve power conservation by rapidly dropping or increasing current so that the output termination voltage(VTT) would be half of the supply voltage(VDDQ). This results in reduced power dissipation and higher efficiency.
Why use DDR Termination Regulators?
DDR Termination regulators are necessary to save power while DDR memory is active. Today, DDR is becoming even faster and more effective in transferring data and this makes the systems powering the DDR memory more susceptible to frequent and inaccurate data transfer. A good DDR Termination Regulator closely tracks supplied voltage and quickly sinks or sources current to maintain a regulated transmission of power. This ultimately leads to a more efficient double data rate memory and an indispensable power solution for a variety of mobile and home devices.
