BEER determines an ECC code's parity-check matrix based on the uncorrectable errors it can cause. BEER targets Hamming codes that are used for DRAM on-die ECC but can be extended to apply to other linear block codes (e.g., BCH, Reed-Solomon). BEER is described in the 2020 MICRO paper by Patel et al.: https://arxiv.org/abs/2009.07985.

HARP is a memory error profiling algorithm (i.e., for identifying error-prone cells) designed for use with memory chips that use on-die error-correcting codes (ECC). This tool uses Monte-Carlo simulation to evaluate HARP and other error profilers. HARP and this tool are described in the 2021 MICRO paper by Patel et al.: https://arxiv.org/abs/210…
