The radiation sensitivity of integrated memory cells increases dramatically as the supply voltage decreases. Although there are some Error Correcting Code (ECC) studies to prevent faults on memories used in space applications, there is no consensus on choosing the best ECC product-type with two-dimensional Hamming to mitigate data faults in memory. This work introduces the Product Code for Space Applications (PCoSA), an ECC product based on Hamming and parity in both rows and columns for use in memory with space-application reliability requirements. The potentialities of PCoSA were evaluated by injecting (i) thirty-six error patterns already available in the literature and (ii) all possible combinations of up to seven bitflips. PCoSA has corrected all cases of the thirty-six error patterns, and it has a correction rate of 100% for any three bitflips, 82.67% for four bitflips, and 69.7% for five bitflips.

集成存储单元的辐射灵敏度随着电源电压的降低而急剧增加。尽管已经进行了一些纠错码（ECC）研究，以防止空间应用中使用的内存出现故障，但在选择具有二维Hamming的最佳ECC产品类型以减轻内存中的数据错误方面尚未达成共识。这项工作介绍了空间应用产品代码（PCoSA），这是一种基于行和列的汉明和奇偶校验的ECC产品，用于具有空间应用可靠性要求的内存中。通过注入（i）文献中已有的36种错误模式和（ii）多达7个位翻转的所有可能组合来评估PCoSA的潜力。PCoSA已纠正了所有36种错误模式的情况，
