Flash memory first came into home with external storage devices (e.g. USB memory devices) at very modest capacities of few MB and have reached to hundreds of GB. Now it has become ubiquitous with applications across myriad of devices ranging from smart phones, to IoT, wearable and consumer electronics. With the explosion in applications, many flash memory protocols came into existence, and let’s talk about one of them - ONFi.
ONFi is Open NAND Flash Interface driven by an industry work group of more than 100 companies from the ecosystem of NAND Flash memory. As ONFi protocol evolved, many versions of the ONFi specification were released with increase in speed from ~50MB/s to ~800MB/s. A new mode was also incrementally added to increase the speed in each version of the ONFi as shown in below chart.
