Abstract
Apparatuses and methods of pulse shaping a pulse signal for programming and erasing a Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) memory cell are described. In one method a pulse shape of a pulse signal is controlled to include four or more phases for programming or erasing a SONOS memory cell. A write cycle is performed to program or erase the SONOS memory with the pulse signal with the four or more phases.
