A method for operating a rewritable, non-volatile memory system having a plurality of physical pages (1'-4'), wherein the method comprises the following steps: in a first state, associating respectively one logical page (1-3; B) of a plurality of logical pages with respectively one physical page of at least a part of the plurality of physical pages, wherein the plurality of logical pages consists of logical pages which an application can access and of at least one logical page which the application cannot access, wherein one of the logical pages which the application can access serves as a reference page and the at least one logical page which the application cannot access serves as a buffer memory; and in later states, changing the associations of the logical pages (1-3; B) with the physical pages of at least a part of the plurality of physical pages according to an established rule by means of which in each of the later states the current associations of the logical pages (1-3; B) with the physical pages of at least a part of the plurality of physical pages can be derived from the current associations of the reference page and of the buffer memory with the physical pages of at least a part of the plurality of physical pages, characterized in that the buffer memory is a logical page which is not visible to the application and thus the buffer memory cannot be accessed by the application, write accesses to the logical pages (1-3; B) are distributed such that each physical page (1'-4') is written on equally often, by the associations between the logical pages (1-3; B) and the physical pages (1'-4') being changed according to a particular rule such that each logical page (1-3; B) is associated with each physical page (1'-4') at least once, so that wear caused by memory accesses is uniformly distributed over all the physical pages (1-4'). in a first state, associating respectively one logical page (1-3; B) of a plurality of logical pages with respectively one physical page of at least a part of the plurality of physical pages, wherein the plurality of logical pages consists of logical pages which an application can access and of at least one logical page which the application cannot access, wherein one of the logical pages which the application can access serves as a reference page and the at least one logical page which the application cannot access serves as a buffer memory; and in later states, changing the associations of the logical pages (1-3; B) with the physical pages of at least a part of the plurality of physical pages according to an established rule by means of which in each of the later states the current associations of the logical pages (1-3; B) with the physical pages of at least a part of the plurality of physical pages can be derived from the current associations of the reference page and of the buffer memory with the physical pages of at least a part of the plurality of physical pages, characterized in that the buffer memory is a logical page which is not visible to the application and thus the buffer memory cannot be accessed by the application, write accesses to the logical pages (1-3; B) are distributed such that each physical page (1'-4') is written on equally often, by the associations between the logical pages (1-3; B) and the physical pages (1'-4') being changed according to a particular rule such that each logical page (1-3; B) is associated with each physical page (1'-4') at least once, so that wear caused by memory accesses is uniformly distributed over all the physical pages (1-4').
