There are three common NOR flash chip configurations:
1. Uniform sector - all sectors are the same size
2. Bottom boot - There are several smaller sectors at the beginning of
memory space. For example, 8 x 8k sectors + 127 x 64k sectors.
3. Top boot - There are several smaller sectors at the end of memory
space. For example, 127 x 64k sectors + 8 x 8k sectors.
I hope this makes sense.
regards,
Ben
