SEMICONDUCTOR MEMORY DEVICE WITH ON-DIE-TERMINATION CIRCUIT

摘要

A semiconductor memory device with an on-die-termination circuit is provided to turn off the on-die-termination circuit through assembly of an applied internal signal without using on-die termination. A driving signal generation unit(100) generates an initialization signal and a positive/negative driving clock by receiving a plurality of control signals. An off-signal generation unit(200) is initialized in response to the initialization signal, and generates a termination off-signal in response to the positive/negative driving clock. A termination resistance supply unit(400) supplies termination resistance according to the setting of a mode register and the termination off-signal. The plurality of control signals is applied through an input pin which is not connected to the termination resistor.
