Radiation-hardened asynchronous static RAMs for extreme environment applications

21-11-2023 | Infineon | Semiconductors

Infineon Technologies LLC Memory Solutions offers its latest rad hard asynchronous static RAMs designed with its patented RADSTOP technology. These new products are developed for usage in space and other harsh environment applications where high reliability and performance are critical.

Data buffering in high-performance space computing needs more memory than the on-chip memory of an MCU or FPGA can provide. The memory must deliver a higher level of performance for real-time processing applications and have superior radiation performance to meet mission needs in harsh environments. The company's new rad hard SRAMs are available in 8-, 16- and 32-bit wide configurations, offering embedded ECC for single-bit error correction. This advanced technology enables the ECC logic to detect and correct single-bit errors in any read data word during the read cycles.

"Radiation effects can cause unavoidable bit errors in SRAMs, and using system-level ECC increases both design complexity and latency," said Dr. Helmut Puchner, vice president and fellow of Aerospace and Defense at Infineon. "Infineon's RADSTOP asynchronous SRAM memories provide an ultra-reliable single-chip solution that solves these issues and meets the radiation performance requirements of the space industry."

The company's state-of-the-art RADSTOP technology is rad hard through proprietary design and process hardening techniques, satisfying all radiation necessities for extreme environments. The new rad hard memories are QML-V certified, providing harsh environments' reliability and lifecycle requirements. The devices feature access times down to 10ns, making them the fastest option available. They also provide the smallest footprint for the highest density and lowest quiescent current. RADSTOP memory solutions extend the computing limits of the overall system while offering size, weight and power advantages for greater design flexibility.
