ABSTRACT:
A new method is indicated for the restore of bitlines and data-lines from memory-cells. All bit- and datalines are switched together during the restore activity so that all restore-FETs can be prepared with the necessary re-charging current. The non-addressed bitlines are then switched off through their bitswitches. In this manner, the dimensions of the re-charging devices can be considerably reduced.
