In this week's Whiteboard Wednesdays, Scott Jacobson completes his three-part series on the Memory Wall with a discussion on the different 3D memory solutions today and their market applications. You may recall that in the first segment, Scott examined how CPU performance outstrips memory transfers, and discussed options available to system designers, such as 2D solutions. In the second part of this series, Scott, took a closer look at 2D memory solutions like EMMC 5.0, UFS, and DDR4.
