Abstract

A method to program bitcells (11, ..., mn) of a ROM array (10) uses different programming cells (0a, ..., 0h, 1a, ..., 1d) for programming the bitcells (11, ..., mn) with a first or second data item. A first bitcell (11) is programmed by means of a selected programming cell, wherein the programming cell is selected in dependence on operating the memory array (10) as a flipped or a non-flipped memory in multi-bank instance. All other bitcells (12, 13) located in the same column (C1) as the first bitcell (11) and subsequent rows (R2, R3) are programmed by selected programming cells, wherein the selection of the programming cells is dependent on operating the memory array (10) as a flipped or a non-flipped memory in multi-bank instance and the programming state of the programming cells used for the previously programmed bitcells in the same column (C1).
