Infineon’s 144Mb Quad Data Rate (QDR^®)-II+, CYRS164x and CYRS264x series, are high performance, synchronous pipelined SRAMs designed with Infineon’s RADSTOP™ technology.  The 144Mb QDR^®-II+ memories are available in x18/x36 and two-word/four-word data bus configurations, and optional on-die termination (ODT).  Our QDR^®-II+ provides low latency and random memory access capability ideal for high speed cache applications.

Infineon’s radiation hardened memories are QML-V certified, meeting the reliability and lifecycle demands of extreme environments. Our RADSTOP^TM memory solutions enhance overall system computing limits while providing Size, Weight, and Power (SWaP) benefits and greater design flexibility.

Infineon’s state-of-the art RADSTOP™ technology is radiation hardened through proprietary design and process hardening techniques.
