Abstract
A semiconductor memory has a data signal path and a control device in order to supply functional elements of the data signal path with control signals. Programmable delays are connected into the signal lines providing the control signals, so that the time relationships between the control signals can be set reversibly via a soft set register or irreversibly via fuses. This enables simple adaptation of the internal control signal timing to fluctuations in the fabrication process or after conversion of the configuration to a new fabrication process.
