Abstract
A semiconductor memory device can automatically control signal transmission power on-chip based on a wireless signal transmission. The semiconductor memory device can have a multi-chip stack structure. A power initializing method of the semiconductor memory device can comprise providing a test signal generated by a signal-providing chip to a first chip, checking whether the test signal provided to the first chip has an error, providing the checking result to the signal-providing chip, setting the power of a first signal provided to the first chip according to the checking result, and setting the power of a signal provided to a second chip adjacent to the first chip and close to the signal-providing chip using the power of the first signal.
