An electronic circuit has a data producing circuit (12), such as a matrix of memory cells. A capture circuit (14) has an input coupled to the data producing circuit (10) for capturing the data signals after allowing a selected part of the data producing circuit to drive the input of the capture circuit. An error detection circuit (15) detects errors in the captured data signals. In response to detection of an error in particular data signals, the error detection circuit causes recapture of the particular data signals, allowing the data producing circuit (10) to drive the data signals at the input of the capture circuit (14) during a second time interval until recapture, the second time interval having a longer duration than the first time interval. This makes it possible to select the duration of the first time interval allowing for average driving speed of circuit parts (e.g. memory cells), without using a duration designed to account for worst case driving speed that may occur due to spread. Errors caused by spread are corrected by rereading with an increased time interval for driving the input of the capture circuit. Preferably, the duration of the first time interval is regulated so that on average a predetermined error rate occurs. ® KIPO & WIPO 2007
