There are two basic processes that allow placing the electrons on the floating gate – Fowler-Nordheim tunnelling and channel hot electron (CHE) injection. Both processes are destructive to the very thin dielectric between the floating gate and the channel of a transistor.

As a result, the number of possible cycles is limited because the floating gate slowly accumulates electrons, causing a gradual increase in the storage transistor’s threshold voltage and programming time. After a certain amount of program/erase cycles (typical values were represented in Table 1) it is no longer possible to erase or program the cell. Another negative effect (which is the main restoring failure mode for Flash memory) is negative charge trapping in the gate oxide. It inhibits CHE injection and tunnelling, changes the write and erase times of the cell, and shifts its threshold voltage.
