16-Mbit, 64-Mbit rad-hard MRAMs
The UT8MR2M8 is a 16-Mbit device offered in a 40-lead flatpack package. The 64-Mbit UT8MR8M8 is a multichip module available in a 64-lead flatpack package. Everspin’s largest monolithic memory is a 16-Mbit device but it looks like Aeroflex is taking four die and wiring them up in a single package to create the 64-Mbit device.
MRAM technology provides a combination of fast access time, non-volatility, data retention and endurance. The parts are architected as non-volatile replacements for SRAM components.
The 3-V MRAMs have guaranteed operation from -40 to +105 degees C, 100-krads(Si) and are SEL immune to more than 100 MeV-cm2. As a replacement for 3.3-V SRAMs, the MRAMs are 8-bit parallel I/O solutions with data retention after each write of 20 years.
"Using an IP license from Everspin Technologies, Aeroflex has taken commercial MRAM technology and modified it for the specialized aerospace and defense markets in less than two years," said Anthony Jordan, director of standard products at Aeroflex Colorado Springs. "Aeoflex MRAMs will be QML Q and we are striving for QML qualification. We are committed as a long-term supplier of memory products for harsh environments."
Prototypes for the UT8MR8M8 are available now with volume production scheduled to start in 2Q13; the UT8MR2M8 prototypes are available now with production due in one year’s time in 3Q13.
