尔必达宣布推出业界第一款基于x32-bit界面的1Gb XDR DRAM内存芯片，运行频率高达7.2GHz，数据传输率(带宽)达到了惊人的28.8GB/s。

相比之下，现在的x16-bit 7.2GHz XDR提供的带宽只有14.4GB/s，而x16-bit DDR3-1333内存更是仅仅3.2GB/s，只不过海力士去年发布的7GHz 1Gb GDDR5也能带来28GB/s的带宽，并不逊色多少。

这种XDR内存采用尔必达65nm CMOS工艺制造，150-ball FBGA封装，工作电压仅1.5V，只需一颗芯片即可提供双x16-bit 512Mb XDR DRAM，相比现在的双芯片方案可节省35-40％的功耗，占用空间也更少。

尔必达已经开始出货7.2GHz XDR内存芯片的样品，批量投产定于今年4月份启动。
