Abstract
A semiconductor structure includes a plurality of pairs of nonvolatile memory cells arranged in a row, an edge cell positioned adjacent to the pairs of nonvolatile memory cells, and first, second, third, and fourth gates. Each pair of nonvolatile memory cells includes first and second nonvolatile memory cells. The first and second gates extend across the first nonvolatile memory cells, the second gate partially overlapping the first gate, and the third and fourth gates extend across the second nonvolatile memory cells, the fourth gate partially overlapping the third gate. Each of the first, second, third, and fourth gates has an end portion that is positioned in the edge cell, and the edge cell includes a protection layer that is positioned over the end portions of the first, second, third, and fourth gates and covers an end face of the second and fourth gates.
