memory RTIMS Flash

Request information



The Radiation Intelligent Memory Stack (RTIMS) Flash is a user-friendly, high density, plug-and-play, radiation-protected NAND Flash memory. Its embeds a Flash Memory Controller (FMC) and NAND Flash memories.

The NAND Flash memories embedded are SLC-based and latch-up immune. The FMC provides module full protection against SEU through TMR -Triple Modular Redundancy or EDAC-Error Detection And Correction. In addition, the protection against high-current SEFi is performed by current detection and power management controlled by the FMC.

First released in 2014, RTIMS Flash can be as a standard NAND Flash when connected to any any processor or FPGA with a built-in NAND Flash interface. It is also used as a small stand-alone local data recorder due to its high level embedded functions such as wear leveling, bad block management, etc.
