    摘要: An address transforming circuit that can change a memory mapping when a system is booted includes a switch control signal generating circuit and an address transforming unit. The switch control signal generating circuit generates alternately enabled switch control signals synchronized with a reset signal. The address transforming unit transforms bits of a first address to generate a second address in response to the switch control signals. Accordingly, a semiconductor memory device including the address transforming circuit has a long lifetime and high reliability.
