Rad-tolerant memory card with up to 1-TB capacity
Aitech Systems has released the S993, a radiation-tolerant 3U CompactPCI memory card that provides up to 1 TB of on-board storage Space NAND flash with all 8 NAND modules installed for a variety of space applications.
Both versatile and performance, the new memory board provides high-capacity, non-volatile Flash memory for reliable data storage in both in-orbit spaceflight and downlink communications to earth-bound base stations.
Vivek Hazari, Director of Engineering at Aitech, noted, “As the amount of data inputs integrated into space electronics continues to grow, having a radiation-tolerant memory board with this much capacity enables companies to keep building more advanced systems for future space applications. The S993 is a gamechanger for on-board memory storage.”
The space-rated memory card includes built-in hardware error detection and correction (EDAC) to correct single-bit errors and detect double-bit errors as well as offers a low single event upset (SEU)-rate and high latch up immunity.
With Aitech’s Flash File Driver (FFD) technology, a POSIX compliant file system with wear leveling implemented and semaphore protection, the board can be accessed as a file system from any cPCI SBC with a Flash File System implemented. The new S993 also includes a Flash Translation Layer (FTL) to handle writes and wear leveling, bad block management and garbage collection, offloading this function from the host processors.
In addition to CompactPCI, future planned interfaces for the S993 includes Space VPX Lite (VITA 78.1) and TSN/TTE Ethernet to further extend the number of space applications with access to high-capacity storage.
