Дык вот, на днях искал человек дополнительную информацию по раскладке данных в протоколе JEDEC. Но никто не высказался в ответ. КМК и по параллельным есть такой документ. http://caxapa.ru/947979.html
JEDEC Publishes New Standard for Serial NOR Flash
ARLINGTON, Va., USA – SEPTEMBER 28, 2011 –JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the availability of JESD216 : Serial Flash Discoverable Parameters (SFDP) for Serial NOR Flash. Widely anticipated by software engineers, the SFDP will allow Serial Flash manufacturers to embed a standard description of important device characteristics inside the Flash chip. Users can read the description and obtain critical information about the functional characteristics and capabilities of SFDP compliant Flash memory devices, which will enable user applications such as mobile phones, set-top boxes, HDTVs, PC/NB motherboards, or any system that needs to support multiple Serial NOR Flash device types, to configure themselves to handle various Serial Flash implementations. JESD216 is available for free download at www.jedec.org.
