Appeal No. 95-1955
Application 08/109,982
(b) allocating a plurality of data stores for a
second one of said non-volatile memories, each data
store having a plurality of buffers containing
redundant data to a respective one of said buffers in
said first one of said non-volatile memory;
(c) providing a data store in each of said non-
volatile memories which data store includes a bit map
buffer having first data therein relating to the status
of each of a plurality of buffers of said respective
non-volatile memory and said respective bit map buffers
includes status data only for that respective non-
volatile memory wherein said first data has a first
state and a second state;
(d) providing and entry table of addresses in said
ROM for accessing the data store in each of said
respective non-volatile memories;
(e) determining a current buffer address for
accessing said respective non-volatile memories in
accordance with the data in said ROM table and said
non-volatile memory bit map;
(f) calculating and storing an associated CRC for
only those data stores having said respective first
data in a first state in each of said buffers of said
respective non-volatile memories wherein said CRC has a
first state representing a good data store buffer and a
second state representing a bad data store buffer;
(g) setting said first data to said first state
when said CRC is in a first state or to said second
state when said CRC is in said [second] state; [and],
(h) programing said microcontrol system to access
only those data stores wherein said first data is in
said first state.
Note that claims 11 and 12 do not require that the second
non-volatile memory contain redundant data with respect to the
buffers in the data stores of the first non-volatile memory.
