Spansion recently introduced a NOR flash that the company boasts is the: “World’s fastest NOR flash memory”. Named HyperFlash, the chip taps into high-speed SPI interface, doubling its width and adding a differential clock to run at an I/O rates as high as 333MB/s.
In this post’s graphic (click to enlarge) Spansion compares the HyperFlash chip’s sustained read rate (right-hand column) to that of (from left to right) asynchronous parallel NOR, single-bit SPI, industry-standard DDR Quad SPI, and Spansion’s faster rendition of DDR Quad SPI, which Spansion tells us, until now, has been the fastest flash on the market. The company points out that HyperFlash is five times the speed of industry-standard Continue reading “Spansion’s Super-Fast HyperFlash NOR”
