Abstract: A memory interface may include a transmitter that generates multi-level signals made up of symbols that convey multiple bits of data. The transmitter may include a first data path for a first bit (e.g., a least significant bit (LSB)) in a symbol and a second data path for a second bit (e.g., the most significant bit (MSB)) in the symbol. Each path may include a de-emphasis or pre-emphasis buffer circuit that inverts and delays signals received at the de-emphasis or pre-emphasis buffer circuit. The delayed and inverted data signals may control de-emphasis or pre-emphasis drivers that are configured to apply de-emphasis or pre-emphasis to a multi-level signal.

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.

Abstract: A memory interface may include a transmitter that generates multi-level signals. The transmitter may employ channel equalization to improve the quality and robustness of the multi-level signals. The channel equalization may be controlled independently from the drive strength of the multi-level signals. For example, a first control signal may control the de-emphasis or pre-emphasis applied to a multi-level signal and a second control signal may control the drive strength of the multi-level signal. The first control signal may control a channel equalization driver circuit and the second control signal may control a driver circuit.

Abstract: Examples of analog delay lines and analog delay systems, such as DLLs incorporating analog delay lines are described, as are circuits and methods for adaptive biasing. Embodiments of adaptive biasing are described and may generate a bias signal for an analog delay line during start-up. The bias signal may be based in part on the frequency of operation of the analog delay line.
