Embedded Memory Engineer

Project

Work done for a product or program.

• Design or integrate embedded NVM macros including array, sense path, high-voltage or write-driver circuits and the macro control interface.
• Qualify embedded MRAM, RRAM or eFlash modules in a logic process node with the foundry, covering module integration and thermal budget constraints.
• Define and verify write, erase and read algorithms including MRAM write pulse shaping, verify-and-retry and error handling.
• Meet automotive requirements for data retention at 150 degrees Celsius grade-0 conditions and endurance cycles across the product lifetime.
• Implement ECC, redundancy and read-margin trim schemes required for embedded NVM data integrity in safety-critical MCUs.
• Support functional safety work by supplying failure-mode data and diagnostic coverage inputs for FMEDA under ISO 26262.
• Characterise macro-level retention, endurance, disturb and magnetic immunity for MRAM including external field robustness.
• Deliver macro integration collateral — timing models, GDS, DRC/LVS-clean views, test collateral and integration guides — to SoC teams.
• Support DFT and production test of embedded NVM including BIST, MBIST, trimming, fuse programming and wafer-level trim flows.
• Evaluate emerging eNVM candidates against eFlash scaling limits and recommend technology selection for future MCU platforms.

Function
