Method for data recording, DETECTION METHOD of access errors and a memory device associates

The present invention relates to a data recording method, a method for detecting access errors in a memory and its associated device. The method of recording a computer data (DW1) to a specified address (ADDR) of a memory (101) comprises a step of writing in memory of a final data (DW2) calculated by a function of said given recording (DW1) and the address (ADDR) to which the data is to be recorded, said function being selected so that said final data (DW2) has a storage size of less than the sum of the respective storage of the dimensions given recording (DW1) and the value of the address (ADDR). The invention applies for example to the memories present in high-reliability computer systems, these memories are volatile or not.
