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.
