Abstract
Methods, systems, and devices for improving uniformity between levels of a multi-level signal are described. Techniques are provided herein to unify vertical alignment between data transmitted using multi-level signaling. Such multi-level signaling may be configured to capture transmitted data during a single clock cycle of a memory controller. An example of multi-level signaling scheme may be pulse amplitude modulation (PAM). Each unique symbol of the multi-level signal may be configured to represent a plurality of bits of data.

A method, comprising:
- determining a timing offset between a first transition between a plurality of amplitudes and a second transition between the plurality of amplitudes, the plurality of amplitudes associated with a data signal output from a transmitter coupled with a driver, the first transition corresponding to first data output from the driver and the second transition corresponds to second data output from the driver;
- initiating an adjustment of a timing output of the first data relative to a timing output of the second data based at least in part on the determined timing offset;
- and
- transmitting the data signal based at least in part on initiating the adjustment of the timing output of the first data.
An apparatus, comprising:
- a multi-leg driver that comprises a first leg operable to output first data that includes at least one bit and a second leg operable to output second data that includes at least on bit;
- a first delay component coupled with the first leg of the multi-leg driver;
- and
- a controller operable to:
- determine a timing offset between a first transition between a plurality of amplitudes and a second transition between the plurality of amplitudes, the plurality of amplitudes associated with a data signal output from a transmitter coupled with a driver, the first transition corresponding to the first data output from the driver and the second transition corresponds to the second data output from the driver;
- initiate an adjustment of a timing output of the first data relative to a timing output of the second data based at least in part on the determined timing offset;
- and
- transmit the data signal based at least in part of initiating the adjustment of the timing output of the first data.
An apparatus, comprising:
- a multi-leg driver that comprises a first plurality of legs operable to output first data and a second plurality of legs operable to output second data;
- a controller coupled with the multi-leg driver and operable to determine a timing offset between a first transition between a plurality of amplitudes and a second transition between the plurality of amplitudes, the plurality of amplitudes associated with a data signal output from a transmitter coupled with a driver, wherein the first transition corresponds to the first data output from the driver and the second transition corresponds to the second data output from the driver, the data signal indicating the first data and the second data;
- and
- a first delay component coupled the multi-leg driver and operable to adjust a timing output of the first data relative to a timing output of the second data based at least in part on the determined timing offset.
