Abstract: A memory device includes a command interface configured to receive write commands from a host device. The memory device also includes an input buffer configured to buffer data from the host device. The memory device further includes a write shifter configured to receive a first write command of the write commands and to shift the first command through the write shifter. The write shifter is also configured to cause the input buffer to be disabled after a first threshold of clock cycles when the first write command has shifted through the write shifter. The write shifter is additionally configured to receive a second write command and prevent the input buffer from being re-enabled until the second write command has shifted through a second threshold of stages of the write shifter.

Abstract: Systems and methods are provided for a memory device that includes a decision feedback equalizer (DFE) reset generator configured to transmit a DFE reset signal to reset taps of a DFE. The memory device also includes an input buffer. The input buffer includes a data branch configured to output data from the input buffer for use downstream in the memory device. The input buffer also includes a DFE reset branch configured to reset the taps for the DFE based on the DFE reset signal. Moreover, resetting the taps using the DFE reset branch does not reset output data of the data branch.

Abstract: At least one of the disclosed systems includes driver logic that is capable of driving a device and pre-driver logic coupled to the driver logic and that drives the driver logic. If the pre-driver logic receives an input signal of a first type, the pre-driver logic activates a first transistor such that the pre-driver logic provides an output signal. If the pre-driver logic receives an input signal of a second type, the pre-driver logic activates a second transistor and a third transistor that together cause the pre-driver logic to provide a different output signal. If the third transistor is not activated, the pre-driver logic provides the output signal.
