Of course, the exploit that they've actually released is completely harmless, but it demonstrates that the CPU cache can be "poisoned" to let folks read and write into the otherwise protected SMRAM memory.

SSDs using NAND flash memory are capable of very fast read and write speeds and thus can make immediate use of such fast interfaces (whereas it takes many SAS HDDs working together to result in data rates even approaching there speeds).

This design will permit the DDR4 memory devices to have separate activation, read, write or refresh operations underway in each unique bank group.
