Abstract
A semiconductor device that has a silicon-oxide-nitride-oxide-silicon (SONOS) based non-volatile memory (NVM) array including charge-trapping memory cells arranged in rows and columns and configured to store one of N×analog values. Each charge-trapping memory cells may include a memory transistor including an angled lightly doped drain (LDD) implant extends at least partly under an oxide-nitride-oxide (ONO) layer of the memory transistor. The ONO layer disposed within the memory transistor and over an adjacent isolation structure has the same elevation substantially.
