Infineon says the new solution is an industry first for radiation-hardened NOR Flash.
Infineon Technologies has recently introduced its 512-Mbit radiation-hardened (rad-hard) NOR Flash memory, marking what the company claims as the first of its kind in non-volatile memory for space applications.
Infineon’s 512-Mbit NOR Flash solution.
Developed with funding from the U.S. Air Force Research Laboratory (AFRL) and the Microelectronics Research Development Corporation (Micro-RDC), the device is said to offer unmatched radiation performance, speed, and density.
Optimized for Space Applications
Infineon’s 512 Mbit NOR Flash (product brief linked) is designed to store FPGA configuration images and standalone boot code for space-grade microprocessors. These systems require rapid initialization and data retrieval, both of which are supported by the device’s 133 MHz Quad Serial Peripheral Interface (QSPI). This interface enables fast data transfer rates, allowing the device to load a 200 Mb FPGA bitstream in just 0.42 seconds, according to Infineon.
Application of the 512-Mbit NOR Flash.
Infineon aimed to combine high performance with enduring reliability in this memory solution. It offers up to 10,000 program/erase cycles, ensuring data retention for a decade even at elevated temperatures of 125°C. The memory operates at a 3.3 V supply voltage, with additional support for 1.8 V input/output. The 512 Mbit density can store multiple FPGA configurations for system redundancy. Additionally, the dual-image capability provides extra assurance against system failure, allowing for fallback options in the event of corrupted data.
A Look at SONOS Technology
At the heart of Infineon’s new solution is its Silicon-Oxide Nitride-Oxide-Silicon (SONOS) charge gate trap technology.
SONOS features a silicon-nitride layer sandwiched between silicon-oxide layers, creating a charge-trapping dielectric within the gate stack of a metal-oxide-semiconductor (MOS) transistor. This structure enables charge storage in discrete traps within the nitride, fundamentally enhancing the memory’s performance and reliability.
The operation of SONOS memory relies on charge injection and retention within the nitride layer. During programming, electrons are introduced into the nitride through Fowler-Nordheim tunneling, a process induced by a strong electric field across the gate. To erase, holes are tunneled back into the nitride layer, effectively neutralizing stored charges.
SONOS transistor cross section.
Unlike conventional floating-gate Flash memory, which suffers from charge leakage in high-radiation environments, SONOS devices maintain their charge integrity even after prolonged exposure to ionizing radiation.
Specifically, the SONOS-based devices offer a total ionizing dose (TID) tolerance of up to 300 krad(Si), a metric for devices exposed to cosmic rays and high-energy particles. Furthermore, the new memory solution provides superior single-event effects (SEE) performance, ensuring immunity to single-event upsets (SEUs) and robust protection against single-event latchups (SELs) at linear energy transfer (LET) values exceeding 80 MeV.cm2/mg at 125°C. Single-event functional interrupt (SEFI) rates are minimized to less than 2.77 × 10?? errors per device daily.
A Step Forward for Space Electronics
Through collaboration with the AFRL and Micro-RDC, Infineon has successfully integrated cutting-edge research into a commercially viable product, setting a new standard in radiation performance and reliability. The new NOR Flash solution is now available for purchase.
