Classification: G11C

Abstract:
A circuit configuration, comprising:a programmable link for permanent storage of a datum; a drive circuit containing: a data input; a complementary data input; a drive circuit output coupled to said programmable link and outputting an energy pulse for activating said programmable link in a manner dependent on a data signal present at said data input; a first transistor having a control terminal connected to said data input; a second transistor having a control terminal connected to said complementary data input; and a volatile memory for storing a datum, said volatile memory containing: an output outputting the data signal being a memory content of said volatile memory, said output connected to said data input of said drive circuit for data communication, said control terminal of said first transistor receiving the data signal; and a complementary output outputting a complementary data signal being complementary to the data signal and connected to said complementary data input of said drive circuit, said control terminal of said second transistor receiving the complementary data signal.
