Abstract
A cellular telephone (10) stores both the programming for its processor (18) and certain changing parameters in the same flash-memory device (36). The device is sectored so that the changeable parameters can be erased without erasing the program contents, and they are stored and fetched in an associative manner so that erasures are required only infrequently.
