Zentel was registered as brand by Powerchip in 2002 for a Japanese DRAM design center, became a DRAM IC manufacturer in Taiwan in 2006, received its first ISO certifications in 2009 and developed standard DRAM ICs from 64Mb to 32Gb memory density with a specific focus on hardware cyber security through chip-integrated RowHammer protection circuits and error correction code with a novel warning output to the controller for timely response to the first excess sporadic bit flip error, before further damage occurs in IoT systems - such as sabotage or spying on OS-protected data such as passwords or crypto keys, whereby software-based protection such as firewalls, AV apps or OS patches are bypassed, thus enabling remote hacking and hijacking of entire networks without leaving forensic traces.
