Abstract
A programmable non-volatile memory supplies of instructions and data to a processing unit. A program stored in the non-volatile memory contains an instruction for jumping to a subprogram in an auxiliary memory. The subprogram changes data in the non-volatile memory for use by the program and returns control to the program in non-volatile memory when completion of the change is detected. Control can be transferred back from the subprogram to one or more instructions in the non-volatile memory after suspension of data changing before said changing is complete. Changing is resumed upon return of control from the one or more instructions to the subprogram.
