  Reducing the threshold voltage of electronic devices increases their
sensitivity to electromagnetic radiation dramatically, increasing the
probability of changing the memory cells' content. Designers mitigate failures
using techniques such as Error Correction Codes (ECCs) to maintain information
integrity. Although there are several studies of ECC usage in spatial
application memories, there is still no consensus in choosing the type of ECC
as well as its organization in memory. This work analyzes some configurations
of the Hamming codes applied to 32-bit memories in order to use these memories
in spatial applications. This work proposes the use of three types of Hamming
codes: Ham(31,26), Ham(15,11), and Ham(7,4), as well as combinations of these
codes. We employed 36 error patterns, ranging from one to four bit-flips, to
analyze these codes. The experimental results show that the Ham(31,26)
configuration, containing five bits of redundancy, obtained the highest rate of
simple error correction, almost 97\%, with double, triple, and quadruple error
correction rates being 78.7\%, 63.4\%, and 31.4\%, respectively. While an ECC
configuration encompassed four Ham(7.4), which uses twelve bits of redundancy,
only fixes 87.5\% of simple errors.
