Abstract
The present disclosure, in some embodiments, relates to an integrated chip. The integrated chip includes a source/drain region arranged within a substrate. A select gate and a memory gate are arranged over the substrate. An inter-gate dielectric structure is arranged between the memory gate and the select gate. A conductive contact is disposed on the source/drain region and vertically extends from a bottom of the select gate to a top of the select gate. The select gate is closer to the conductive contact than the memory gate. The select gate has a first outermost sidewall that faces away from the memory gate and a second outermost sidewall that faces the memory gate. The first outermost sidewall is taller than the second outermost sidewall.
