ABSTRACT:
To control selection of content in a non-volatile memory, control information is stored in the non-volatile memory, where the control information is to control selection of content in the non-volatile memory. An algorithm is used to update the control information in the non-volatile memory to cause different content in the non-volatile memory to be selected, wherein the algorithm sets the control information to an initial value that enhances use of programming of the non-volatile memory to update the control information, and reduces use of erasing of the non-volatile memory to update control information.
