The Intel® Wireless Flash Memory (W18) device with flexible multi-partition dual operation,
provides high-performance asynchronous and synchronous burst reads. It is an ideal memory for
low-voltage burst CPUs. Combining high read performance with flash memory’s intrinsic non-
volatility, the W18 device eliminates the traditional system-performance paradigm of shadowing
redundant code memory from slow nonvolatile storage to faster execution memory. It reduces
the total memory requirement that increases reliability and reduces overall system power
consumption and cost.
The W18 device’s flexible multi-partition architecture allows programming or erasing to occur
in one partition while reading from another partition. This allows for higher data write
throughput compared to single partition architectures. The dual-operation architecture also
allows two processors to interleave code operations while program and erase operations take
place in the background. The designer can also choose the size of the code and data partitions via
the flexible multi-partition architecture.
