An adaptive procedure of error recognition and the error correction, which it makes possible, is described partial defective memory elements (e.g. FLASH memory to be able to use magnetic disks and magnetic tapes) at least with reduced storage capacity again. DOLLAR The memory element must become upstream a microprocessor of steered CONTROLLER, which makes an analysis of the memory-internal error structure during the initialization. According to the structure of these errors either a Reed Solomon (R-S) is used code of small correction ability, R-S code of high correction ability or R-S product code, in order to be able to use the remaining storage capacity optimally. DOLLAR A depending upon application error detection and error correction can be realized separately into Hardwareund software components. The microprocessor steered CONTROLLERs takes over thereby beside the general store management also rare necessary, but more complex algorithms of R-S error correction. Simpler one, often necessary routines of R-S algorithms for the coding and error recognition (syndrome formation) in a dedicated hardware are realized.
