This paper presents the results of DDR3 SDRAM stuck/weak bit studies from HI, TID, Neutron, Proton and temperature tests. The objectives include identifying reasonable engineering solutions to either ...

Over the past 25 years we have seen the transition from sdram (Synchronous Dynamic RAM) to ddr (Double Data Rate) SDRAM, and then to DDR2, DDR3 and DDR4 on a cadence of five year cycles. Currently we ...
