Abstract
The present invention discloses an input buffer circuit of a synchronous semiconductor memory device comprising a differential amplifier type input buffer and a low current type input buffer, wherein the differential amplifier type input buffer is operated in a normal mode, and the low current type input buffer is operated in a self-refresh mode, thereby decreasing the current flowing through the input buffer in the self-refresh mode. According to the input buffer of the synchronous semiconductor memory device, the current flowing through the input buffer in the self-refresh mode is very small, therefore the power consumption of the synchronous semiconductor memory device can be reduced.
