Abstract
A semiconductor integrated device having a plurality of memory cells, each including a floating gate, a control gate and an auxiliary gate formed over a side surface of the floating gate through an insulator film. Auxiliary gates coupled to selected memory cells function to generate hot electrons and are alternately arranged with other auxiliary gates functioning to prevent write errors in the non-selected memory cells.
