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.
