First ceramic hermetic DDR2 memory suitable for space

Data Device Corporation (DDC) has introduced what is claimed to be the first CCGA Rad-Hard DDR2 SDRAM for space applications, the newest addition to their broad range of high-density space grade ceramic hermetic memories, covering Flash (NAND/NOR), SDRAM, SRAM and EEPROM solutions. The new DDR2 (97D2H) provides up to 8Gb of SDRAM in a compact CCGA package, giving an extremely reliable and flexible memory solution for long, dependable use and efficiency of design. The hermetic ceramic packaging gives excellent radiation tolerance for TID (>100krad orbit/mission dependent) and Single Event Effects (no latch-up), while the universal package contains multiple density and data width options to allow simplified board design, system integration and error correction implementation.

“DDC’s hermetically sealed ceramic DDR2 represents the next generation of space level SDRAM, offering the highest radiation tolerance (>100krad) possible, while featuring a wide range of data bus options to allow for simple connectivity with rad-hard FPGAs, ASICs and processors”, stated Dan Veenstra, business unit manager – Space.
