Question

different between read and write in memory

Answer 1

Both read and load can be input operations, but read focuses on the source of that input whereas load focuses on the destination of that transfer. Similarly the object of a write is the destination of the data transfer (e.g. you write (to) memory or write (to) a device register

Answer 2
