Abstract
A method for the parallel programming of memory words in electrically programmable non-volatile semiconductor memory devices comprising at least one matrix of floating gate memory cells with corresponding drain terminals heading columns or bit lines of the matrix and supplied during the programming stage with a drain voltage which is boosted with respect to a supply voltage (Vcc). During the parallel programming stage the supply voltage is used as a drain voltage. Switching is provided between the supply using the drain voltage or the supply voltage during the transient between single word programming and parallel programming.
