Work History
Nand Flash Logic Operation Test Engineer
Samsung Electronics
Hwaseong, Republic Of Korea
08.2023 - Current
Operated and supported test floor equipment (MUST32, Prober) for wafer-level NAND Flash logic verification.
Independently developed a Python-based logic signal waveform analysis tool to identify root causes of z-address failures in customer logic scenarios, particularly in PIR Cache operations.
Enabled in-depth analysis of logic signals up to 40 seconds long, automating detection of command misalignment and AC parameter pin timing issues. Tool is still actively used for high-volume waveform verification by internal teams.
Contributed to NPI projects by validating early silicon and developing test strategies tailored to new product features.
Automated test log parsing and failure pattern analysis, significantly reducing manual debug effort.
Troubleshot hardware/software issues in both high-volume production and customer-specific application test environments.
Bridged production and development phases by feeding back test floor insights into upstream verification improvements.
