Abstract: Apparatus for storing data and a method of adapting a duration of a wordline pulse in an apparatus for storing data are provided. Sensor circuitry comprises a calibrated bitcell which is calibrated to use a duration of wordline pulse which matches a longest wordline pulse required by any bitcell in an array of bitcells for a successful write operation to be carried out. The duration of wordline pulse is signalled to wordline pulse circuitry, which generates a wordline pulse for the array of bitcells with this wordline pulse duration. The sensor circuitry is configured to adapt the wordline pulse duration in dependence on current local conditions in which the apparatus operates to compensate for influence of the current local conditions on the longest wordline pulse required by any bitcell in the array of bitcells.
