Method and apparatus for emulating a byte wise programming functionality into a sector wise erasable memory device

摘要

Method of and system for emulating a byte-wise programmable memory in a sector-wise erasable memory (3), based on the following actions:
a) dividing the sector-wise erasable memory in a plurality of sectors (36),
b) dividing each of the sectors into several memory locations suitable to store containers (35), each container (35) having a header (33) and a payload portion (34),
c) storing a data value relating to an application in the payload portion (34) of one of the containers (35) and header information identifying the application in the header (33) in an available container.
The containers are block containers. The data portion has two or more payload values. The storing action is performed in such a way that the two or more payload values in the payload portion (34) together uniquely represent the data value.
