Abstract: A memory management method for a digital answering system having a non-volatile memory, e.g., flash memory, for storing files of audio messages. In accordance with the method, a first portion of the memory is dedicated for the storage of file information, and a second portion for the storage of message data. A number of rotary storage areas are defined within the first memory portion, with said file information being stored within only one of the rotary storage areas at any given time. Following a predetermined number of write operations to the one storage area, its contents are transferred to another one of the rotary storage areas. A file allocation table is employed which maps the memory of the flash memory. A directory includes directory entries which provide a first row for message data. A data area where messages are stored includes pointers to a next sequence or word in the memory such that a chain of words or sequences in a message file are retrieved in a single access to the first portion of memory.
