Abstract
A memory system (,) incorporating a plurality of memory devices (,) at least one of which has a defective location. Defects are mapped in a non-volatile memory (,). Data structures are divided into portions which are respectively stored in different ones of the memory devices (,). The controller (,) of the system accesses the non-volatile memory so as to generate on a per device basis an address corresponding to a non-defective location in that device. In this system, different addresses may therefore be applied to different ones of the devices (,) when a data structure is written to or read from the memory devices.
