    摘要: A refresh control circuit in a semiconductor memory device includes a refresh controller, a voltage generator and a word line enable circuit. The refresh period controller generates a control signal in response to a self-refresh signal, the control signal indicating a nominal initiation of a refresh period. The voltage generator generates an output voltage in response to the control signal. The output voltage is boosted from a low voltage to a high voltage during the refresh period. The word line enable circuit generates a word line enable signal in response to the control signal, wherein the word line enable signal is activated following a delay after the nominal initiation of the refresh period, and the delay allows the voltage generator to fully boost the output voltage.

Each chip includes “j” corresponding upper and lower electrodes, wherein j is a minimal natural number greater than or equal to n/2, and an identification code generator including a single inverter connecting one of the j first upper electrode to a corresponding one of the j lower electrodes. The upper electrodes receive a previous identification code, rotate the previous identification code by a unit of 1 bit, and invert 1 bit of the rotated previous identification code to generate a current identification code. The current identification code is applied through the j lower electrodes and corresponding TSVs to communicate the current identification code to the upper adjacent chip.
