Interfaces and die packages, and appartuses including the same
First Claim
1. An interface, comprising:
- an output multiplexer configured to divide output data to provide a first data and a second data in response to an external control signal, the output multiplexer being further configured to provide a first control signal and a second control signal;
a first pre-driving circuit configured to provide a first pull-up signal and a first pull-down signal in response to the first data and the first control signal;
a first output buffer configured to provide a first output data in response to the first pull-up signal and the first pull-down signal;
a second pre-driving circuit configured to provide a second pull-up signal and a second pull-down signal in response to the second data and the second control signal; and
a second output buffer configured to provide a second output data in response to the second pull-up signal and the second pull-down signal.

Abstract
A memory device includes a memory die package including a plurality of memory dies, an interface device including an interface circuit, and a memory controller configured to control the interface with control data received from at least one of the plurality of memory dies. The interface device of the memory device is configured to divide and multiplex an IO channel between the memory die package and the memory controller into more than one channel using the control data receive from the at least one of the plurality of memory dies. The interface device for a memory device includes a control input buffer configured to receive an enable signal through a control pad, a first input buffer configured to receive a first data through a first IO pad in response to a first state of the enable signal, and a second input buffer configured to receive a second data through a second IO pad in response to a second state of the enable signal. The interface device further includes an input multiplexer configured to multiplex the first data and the second data to provide an input data.
