Abstract
An EEPROM with two-transistor memory cells with source-side selection, and a method for triggering such a EEPROM are described. The EEPROM and the method are distinguished in that the programming voltage required to program a memory cell is delivered via a source line. As a result the EEPROM can be protected in a simple way against unintended loss of the data stored in it.
