4.3.4.3 Cell Read Disturb
Purpose:
To measure read disturb influence on 56k8 memory cell.
Test parameters:
Lot:
0t0348
Programming: 14V on WL and sensegate @5ms
Temperature: 25°C and 140°C
The cell is stressed with BL voltage much higher than standard read conditions (around 6V) to accelerate disturb
phenomenon : electrons from the Floating gate can move through the tunnel oxide. This charge loss is measured
after stress by a Vt measurement.
Test results:
0t0348 #01 56.8k (568A6)
BL read disturb @25C
16 Rev. 0 – 2003 July
Conclusion:
Extrapolation to 10 years lifetime give a maximum BL voltage of around 4V in read operation, which is much higher
than nominal BL read voltage (~1V). So there is no sensitivity to read disturb either at room temperature or high
temperature.
