Abstract
A method and a device for single event effect testing of large capacity solid state drives based on high-energy particles are provided. The testing method includes: performing a solid state drive (SSD) user data preset experiment; performing irradiation testing using the device; detecting errors of single event latch-up and functional interruption under irradiation conditions; performing silent data corruption testing in a post-irradiation phase; recording silent data corruption and stuck bit error data; and performing error characteristics calculation.
Claims6
A method for single event effect testing of large capacity solid state drives based on high-energy particles, comprising:
- performing an solid state drive (SSD) user data preset experiment, directing data packets according to a specified size into data of an SSD under test and adding verification information to each of the data packets;
- initiating irradiation testing based on the SSD user data preset experiment, judging whether electronic components in the SSD experience functional interruption or single event latch-up under irradiation conditions, and determining a judgment result;
- performing functional testing according to the judgment result, obtaining a functional testing result, and performing silent data corruption testing and stuck bit error testing in a post-irradiation testing phase based on the functional testing result;
- according to the silent data corruption testing and the stuck bit error testing, recording a number of silent data corruption data blocks and stuck bit error data;
- and
- based on the number of the silent data corruption data blocks and the stuck bit error data, performing a quantitative calculation of error characteristics, and outputting a calculation result.
