A method for checking the functional ability of a memory element having a stack memory, wherein the stack memory occupies a defined region within the memory element. A stack memory pointer is defined, which displays, in the form of an address, a stack memory position, from which data are currently being removed or to which data are currently being written. In the memory element, a section of defined length arranged outside a memory region to be checked is delimited and used as an auxiliary memory; the current address of the stack memory pointer is stored before the start of a test program for checking the memory element and the stack memory pointer is then assigned an address associated with the auxiliary memory, so that during the test program the auxiliary memory is used as working memory; and after terminating the test program the stack memory pointer is reassigned the address of that position, which it displayed before the start of the test program.
