Non-volatile Flash memories are becoming more and more popular in Systems-on-Chip (SoC). Embedded Flash (eFlash) memories are based on the well-known floating-gate transistor concept. The reliability of such type of technology is a growing up issue for embedded systems; endurance and retention are of course the main features to analyze. To enhance memory reliability current eFlash memories designs use techniques such as Error Correction Code (ECC), Redundancy or Threshold Voltage (VT) Analysis. In this paper, a memory model to evaluate the reliability of eFlash memory arrays under distinct enhancement schemes is developed.
