摘要:
A description is given of a method for operating an integrated memory which has memory cells each having a selection transistor and a storage capacitor with a ferroelectric storage effect. The memory contains a plate line, which is connected to one of the column lines via a series circuit containing a selection transistor and a storage capacitor of respective memory cells. A memory access is carried out according to the “pulsed plate concept”. In this case, the temporal sequence is controlled in such a way that, in an access cycle, the storage capacitor of the memory cell to be selected is in each case charged and discharged by the same amount. An attenuation or destruction of the information stored in the memory cells, which is caused by source-drain leakage currents of unactivated selection transistors, is thus avoided.
