MemoryAccess
The MemoryAccess microinstruction transfers (copies) data between a register and a RAM. The number of bits transferred is equal to the width of the register. If the cells of RAM are wider than the register, then the register only reads or writes the leftmost (high order) bits of the cell. If the register is wider than the cells of RAM, then the microinstruction will continue reading or writing bits (starting with the high order bits) in successive registers until all bits in the register have been read or written.
Parameters:
Memory: the RAM to or from which data is to be transferred.
Data: the register to or from which data is to be transferred.
Address: the register that contains the address indicating where in the RAM the data is to be read or written.
