A 32-Mbit device will have eight partitions; a 64-Mbit device will have 16 partitions; a
128-Mbit device will have 32 partitions. Each main block is 32-Kword in size.
The 1.8 Volt Intel
Wireless Flash Memory with 3 Volt I/O supports CPUs that boot from either the
top or bottom of the flash memory map. A top parameter flash device has the highest addressable
32-Kword block divided into eight smaller blocks. Conversely, a bottom parameter flash device has
the lowest addressable 32-Kword block divided into eight smaller blocks. Each of these eight 4-
Kword blocks are called parameter blocks. Parameter blocks are useful for frequently stored data
variables. Their smaller block size allows them to erase faster than main blocks. Page- and burst-
mode reads are also permitted in all blocks and across all partition boundaries.
It should be mentioned that the SRAM does not adhere to this multi-partition architecture. The
SRAM memory is organized as a single memory array.
