Micron® Xccela™ Flash Memory

Xccela ™ flash memory sets a new record for NOR flash speeds to meet the demand for instant-on performance and fast system responsiveness in automotive, industrial, consumer and networking applications. With Xccela flash, system designers no longer have to choose between the performance of parallel NOR and the small footprint of serial NOR. Our Xccela flash uses a new interface with as few as 11 active signals. It delivers 5X performance while reducing pin count by 4X, energy consumption by 3X and package size by 2X compared to the page mode parallel NOR solution. In addition to enabling one of the fastest possible direct code execution and shadowing, Xccela flash paves the way for simpler system designs, lower system costs and lower energy consumption.

Key Features and Benefits
