ABSTRACT:
A floating gate type field effect transistor increases the threshold during an application of a write-in pulse to the control gate electrode thereof so as to inject hot electrons into the floating gate electrode, and the write-in pulse is decayed along a waveform having a gradient smaller than a gradient of a pulse signal assumed to take place in a source/drain region of a non-selected floating gate type field effect transistor sharing the selected word line with the selected floating gate type field effect transistor, thereby preventing the non-selected floating gate type field effect transistor from the gate disturb phenomenon.
