Row Hammer. The problem no DRAM vendor wants to talk about, except for one, Zentel

Zentel’s new DDR3 DRAM has published data showing zero Row Hammer failures.  I fondly recall talking to a large vendor’s ‘tiger team’ concerning Row Hammer failures a few years back.  I asked them what should their DDR3 users do if they start to experience Row Hammer failures.  Their response? ‘Upgrade to DDR4!’.  ‘How convenient’ I responded, ‘forcing the industry to throw away all those DDR3 based systems so you can sell more DDR4’.  And come to find out, DDR4 although a bit better, still experienced Row Hammer failures! We here at FuturePlus Systems are glad to see our colleagues in academia are still hunting down those Row Hammer vulnerabilities (https://rambleed.com/).  They can feel good about causing the industry to look for solutions, and it appears that Zentel has answered the call. To the best of our knowledge Zentel has the ONLY Row Hammer hardened DDR3 memory on the market.  See the Zentel data sheets here.  #rowhammer, #DDR3, #JEDEC, #AP Memory,...

FS2600 R/LRDIMM

    FS2600 DDR5 RDIMM/LRDIMM Interposer exclusively for use with the Keysight U4164A logic analysis modules The fastest DDR capture tools in the industry…AGAIN! The FS2600 is our newest and fastest logic analyzer probe used to test DDR5 RDIMM and LRDIMM memory. It is designed to work exclusively with 4 Keysight U4164A logic analysis modules operating in either Quad Sample State or Quarter Channel 10GHz timing modes. This gives the user an extremely effective tool for debugging, testing and verifying DDR5 RDIMM/LRDIMMs and DDR5 Memory Channels. Interposer Design – The FS2600 DDR5 DIMM probe does not sacrifice a memory slot, so you can probe any RDIMM/LRDIMM, even in a fully populated memory bus. FS2601 DDR5 UDIMM Interposer pending JEDEC final pinout (Available NOW!) FS2602 DDR5 SODIMM Interposer pending JEDEC final pinout (Available NOW!) FS2605 DDR5 DIMM Satellite Interposer for Slot 2 same channel (Available NOW!) All signals are probed passively. Complete and accurate State analysis. Quarter Channel Timing mode provides deep 10GHz asynchronous sampling of all Data signals. Measure signal integrity of each bit on the DDR5 DIMM with Keysight EyeScan application. View Example Screenshot. Compatible with latest JEDEC RDIMM and LRDIMM pinout. Quick and easy interposer connection between the DDR5 RDIMM/LRDIMM memory bus connector and the U4164A Keysight logic analyzer module. Provides for both CHA and CHB full Data and Address/Command/Control decode. Short DDR5 probe etch length makes it more reliable in marginal systems. Note: FuturePlus has carefully simulated and designed this FS2600 probe to work in your system and it extends the DDR5 bus less than 1.0 inch. Other factors can have a significant effect on the...
