Multiple Page Write Usage Model
The BIOS usage model requires that the Serial Flash device support multiple writes to a
page (minimum of 512 writes) without requiring a preceding Erase command. The
BIOS commonly uses capabilities such as counters that are used for error logging and
system boot progress logging. These counters are typically implemented by using byte
writes to increment the bits within a page that have been designated as the counter.
The BIOS multiple page write usage model applies to sequential and non-sequential
data writes.
This usage model requirement is based on any given bit only being written once from a
1 to a 0 without requiring the preceding erase. An erase is required to change bits back
to the 1 state.
