Abstract
A method for operating a serial non-volatile semiconductor memory in which, for safely writing data into the semiconductor memory, a serial write sequence is applied to an input terminal. The sequence is formed at least with a sequence of command bits, a sequence of address bits and a sequence of data bytes. During the transmission of the bits of the write sequence, a clock signal is present at a clock input and a sufficiently high supply voltage is present at a supply voltage terminal. On occurrence of a supply voltage that is too low, the write sequence and/or the clock signal is subsequently transmitted incorrectly during the transmission of the write sequence and of the clock signal to the semiconductor memory. In the alternative, the write sequence is not transmitted at all.
