Space-rated memory includes built-in hardware error detection and correction, detects double-bit errors, offers low SEU, and high latch up immunity.

CHATSWORTH, Calif. – Aitech Defense Systems Inc. in Chatsworth, Calif., is introducing the S993 radiation-tolerant 3U CompactPCI memory card for space applications.

The memory card provides as much as 1 terabyte of on-board storage Space NAND flash with all 8 NAND modules installed. It provides high-capacity non-volatile Flash memory for data storage for in-orbit spaceflight and downlink communications to Earth-bound base stations.

The space-rated memory card includes built-in hardware error detection and correction (EDAC) to correct single-bit errors and detect double-bit errors, and offers a low single event upset (SEU)-rate and high latch up immunity.

The radiation-tolerant memory board offers Aitech's Flash File Driver (FFD) technology, a POSIX-compliant file system with wear leveling, and semaphore protection.

Systems can access the board as a file system from any CompactPCI single-board computer with a Flash File System implemented. The 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.

Future planned interfaces for the S993 includes Space VPX Lite (VITA 78.1) and TSN/TTE Ethernet to extend the number of space applications with access to high-capacity memory storage.
