3D PLUS Radiation Tolerant MRAM Sample

Magneto-resistive Random Access Memory (MRAM) stores data using magnetic polarisation rather than electric charge, which brings the MRAM unlimited read/write endurance and Single Event Upset (SEU) immune characteristics.

3D PLUS’s Radiation Tolerant MRAM is available in a variety of temperature ranges and stacks of 1 Mb to 64 Mb organised x8, x16, x32, and x40 with a power supply of 3.3 V and a clock rate / access time of 40 ns. These components have a proven lifetime for 15- to 18-year space missions (specified at 20 years data retention) and have the following radiation tolerance characteristics: TID >50 krad(Si) and SEL >85 MeV.cm3/mg. While there is no pure tin guarantee, 3D PLUS is willing to guarantee less than 97% tin.

3D PLUS’s Radiation Tolerant MRAM devices are offered with a standard SOP footprint for high-resistance SMT assembly and for withstanding harsh thermal and mechanical environments. 3D PLUS MRAM products are used as a processor’s boot and program ROM and FPGA configuration memory in applications spanning sciences and deep space missions, earth observations, navigation, launchers and manned space vehicles, and telecommunications satellites.
