4.0–4.8 Gbps XDR memory channel for graphics intensive consumer applications

Abstract

A 3.2 Gbps XDR™ memory channel has been optimized to achieve a bit rate of 4.8 Gbps. The 24-bit wide memory interface can deliver an aggregate data bandwidth of 14.4 GB/s to support graphics intensive consumer applications such as high refresh rate 3D digital TV. The optimized high performance channel is also designed to satisfy the low-cost constraint of consumer electronics by using wirebond packaging for the SoC and 4-layer PCB.
