New class of rad-tolerant memory card has 1TB capacity
Aitech has developed a 3U compactPCI non-volatile memory board for space applications with plans for Space VPX Lite (VITA 78.1) and TSN/TTE Ethernet.
The S993 supports up to 1Tbyte of NAND flash in eight modules for space flight and downlink applications with built-in hardware error detection and correction (EDAC). An offload processor runs Aitech’s Flash File Driver (FFD) technology, a POSIX compliant file system with wear leveling implemented and semaphore protection. This means 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.
“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,” said Vivek Hazari, Director of Engineering at Aitech.
Pratish Shah, General Manager of Aitech US, commented, “We not only seek to stay current with system advances for our clients, but we also aim to anticipate and exceed the needs and expectations of the space industry. The S993 is the latest example of how Aitech is developing solutions for the innovations being developed throughout space missions across all orbit levels.”
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 memory storage.
