In load/store architecture, memory is only referenced by load and store instructions.
true
false

True

Explanation: Load-store architecture is the architecture in the computer system field that  contains the instruction collection.These sets of the instructions are dived in the two parts named as the ALU(arithmetic and logical) operation section and memory access section.

The ALU operation part handles the arithmetic calculation and evaluation between the registers whereas the memory access part handles the load and store actions only between the register and memory.Thus , the given statement is true.
