Applying the above test to differently programmed and erased chips we were able to build the diagrams for threshold voltage dependence in the Flash program memory from different factors such as the number of erased cycles (Figure 47) and memory address. As can be seen, the charge is not entirely removed from the floating gate even after one hundred erase cycles thus making it possible for the information to be extracted from the memory. This was measured on a sample after 100 program/erase cycles to eliminate the effect of the threshold shift taking place in a virgin cell.
