Methods and apparatuses for differential signal termination

An apparatus comprising:

• a signaling bus;
• a plurality of memory dice, each of the plurality of memory dice comprising:
• a memory cell array;
• and
• a tristate transmitter connected with the signaling bus, the tristate transmitter configured to provide a data signal on the signaling bus responsive to a corresponding control signal;
• and
• a logic die comprising:
• a receiver connected with the signaling bus, the receiver configured to receive the data signal from the signaling bus;
• and
• a circuit configured to provide a predetermined input voltage for the receiver such that the receiver can determine whether the predetermined input voltage is data “0” or “1” when all the tristate transmitters connected with the signaling bus are switched to high-Z responsive to the corresponding control signal.

A method comprising:

• transmitting, with a tri state transmitter of a memory die comprising a memory array, a data signal on a signaling bus to a receiver;
• transitioning the tristate transmitter to a high impedance state;
• and
• providing, with a termination circuit of a logic die coupled to the memory die, a predetermined input voltage for the receiver by coupling an input of the receiver to at least one of a first voltage source or a second voltage source having a different voltage level than the first voltage source such that the receiver can determine whether the predetermined input voltage is logic “0” or “1”, responsive to completion of transmitting the data signal and transitioning the tristate transmitter to the high impedance state.
