摘要： According to one aspect, an on-die termination (ODT) circuit is controlled during transition from a first power mode to a second power mode of a memory device. The transition from an asynchronous ODT circuit path to a synchronous ODT circuit path is delayed to compensate for an operational latency of a delay locked loop (DLL) circuit.

摘要： For determining an on die termination (ODT) mode in a semiconductor memory device, a first mode determining unit determines whether or not a normal ODT mode is enabled from performing a logic operation on a first set of signals. A second mode determining unit determines whether or not a dynamic ODT mode test is enabled from performing a logic operation on a second set of signals. One of the normal and dynamic ODT modes is enabled with more flexibility.

摘要： 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.
