CYRS1645KV18-250GCMB

综述

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 RADSTOPTM 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.
