TRUE. Variable length instruction architectures are better at memory efficiency than fixed length architectures.

Explanation:

Variable length instruction architectures use memory efficiently than fixed length architectures. Fixed length instructions are used in RISC (Reduced Instruction Set Computers), where as CISC (Complex Instruction Set Computers) have instructions of variable length. In fixed instruction length architectures if the instruction has shorter length than that of fixed length it requires padding to increase the instruction length to fixed length. This is wastage of memory.
