Remember the RowHammer memory attack from many moons ago?? Well, it's back in a new form despite numerous mitigations that memory manufacturers have put in place to prevent this style of attack.  A group of researchers from ETH Zurich and Vrije University in Amsterdam indicate that the series of Target Row Refresh (TRR) mitigations that were put in place after Rowhammer was first discovered have been bypassed. With RowHammer, an attack is perpetrated by "hammering" away at a single "row" of memory cells in a module until a bit-flip occurs in an adjacent row. This can cause the value of the data in the bits to change from 1 to 0 (or 0 to 1), leading to memory corruption or even... Read more...
Samsung Electronics has launched the highest capacity mobile DRAM for smartphones promising it will power next-gen experiences for devices. Samsung's new memory tech is the industry's first 12GB low-power double data rate 4X, or LPDDR4X, package that is optimized for premium smartphones. The new chips provide higher capacity than most ultra-thin notebooks offer, and should give smartphone users plenty of headroom to tackle more demanding applications in the future. Samsung promises a seamless user experience for features like multiple-cameras, 2x screen sizes, AI, and 5G connectivity. Samsung notes that the 12GB mobile DRAM will maximize the potential of devices that have more than five... Read more...
