SD is a derivative standard from MMC (which started as slim 7 contacts memory modules), before they diverged, adding 4bits, 8bits, DDR protocols. It is possible to detect the module type during the initialisation sequence. MMC is a JEDEC standard, SD is covered by patents. WebProcessor P1 writes X1 in its cache memory using write-invalidate protocol. So, all other copies are invalidated via the bus. It is denoted by ‘I’ (Figure-b). Invalidated blocks are also known as dirty, i.e. they should not be used. The write-update protocol updates all the cache copies via the bus. ray thacker cartersville ga
