Product Features
The 1.8 Volt Intel
Dual-Plane Flash memory 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 nonvolatility, 1.8 Volt Dual-Plane Flash memory 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 increase reliability and reduces overall
system power consumption and cost.
The 1.8 Volt Dual-Plane Flash memory’s two partitions allow background programming or erasing to occur
in one partition while program-execution reads take place in the other partition. This allows for higher data
write throughput compared to single partition architectures. The dual partition architecture also allows two
processors to interleave code operations while program and erase operations take place in the background.
1.8 Volt Dual-Plane Flash memory is manufactured on Intel
0.25 μm ETOX VI process technology. It is
available in an industry-standard μBGA* CSP package which is ideal for board-constrained applications.
