Abstract
A storage system includes an interface and storage circuitry. The interface is configured to communicate with a plurality of memory cells coupled to multiple Bit Lines (BLs). The memory cells are programmed and read in sub-groups of multiple BLs, and the sub-groups correspond to respective addresses. The storage circuitry is configured to generate a sequence of addresses for reading memory cells that together store a data part and a pattern part containing a predefined pattern, via multiple respective sub-groups, to detect that the data part read from the memory cells is erroneous due to a fault that occurred in the sequence of addresses by identifying a mismatch between the pattern part read from the memory cells and the predefined pattern, and, in response to detecting the fault, to take a corrective measure to recover an error-free version of the data part.
