Optimal ddr4 system with data bus inversion

WebGDDR5 and DDR4 memories use data bus inversion (DBI) coding to reduce termination power and decrease the number of output transitions. Two main strategies exist for encoding data using DBI: DBI DC minimizes the number of outputs transmitting a zero, while DBI AC minimizes the number of signal transitions. We show that neither of these … WebMay 1, 2009 · The most commonly used bus coding technique is data bus invert (DBI) coding [9,15, 16, 17], which encodes a group of multiple data bits by pairing with a single extra control bit.
