Intel Advanced+ Boot Block Flash Memory (C3)
2.5
Memory Map
The C3 device is asymmetrically blocked, which enables system code and data integration within a
single flash device. The bulk of the array is divided into 32 Kword main blocks that can store code
or data, and 4 Kword boot blocks to facilitate storage of boot code or for frequently changing small
parameters. See Table 3, “Top Boot Memory Map” on page 15 and Table 4, “Bottom Boot Memory
Map” on page 16 for details.
