摘要
A method and circuit for blocking unauthorized access to at least one memory cel lin a semiconductor memory. The method includes providing a switch and/or a link which assumes an open state when access to the at least one memory cell is to be blocked; and coupling a data line associated with the at least one memory cell to a constant voltage source is response to the switch or link assuming an open state.
