Abstract
A circuit structure for reading data contained in an electrically programmable/erasable integrated non-volatile memory device includes a matrix of memory cells and at least one reference cell for comparison with a memory cell during a reading phase. The reference cell is incorporated in a reference cells sub-matrix which is structurally independent of the matrix of memory cells. Also provided is a conduction path between the matrix and the sub-matrix, which path includes bit lines of the sub-matrix of reference cells extended continuously into the matrix of memory cells.
