Spansion developed the HyperFlash NOR memory devices, based on the HyperBus interface. The family features read throughput of up to 333 megabytes per second—more than five times faster than ordinary Quad SPI flash currently available with one-third the number of pins of parallel NOR flash. Spansion HyperFlash memory devices provide a migration path—from single Quad SPI to Dual Quad SPI to HyperFlash Memory—allowing system applications to be scaled to different levels of flash performance when paired with compatible controllers, giving OEMs the ability to offer different product models with a single design.
