Abstract
Methods, systems, and devices for feedback for multi-level signaling in a memory device are described. The memory device may use pulse amplitude modulation (PAM) signaling (e.g., PAM4) that is synchronized with a clock signal using a double data rate (DDR) to communicate information with a host device. The memory device may include a first circuit for determining voltage levels of sampling events associated with a rising edge of the clock signal and a second circuit for determining voltage levels of sampling events associated with a falling edge of the clock signal. A feedback circuit may receive a feedback signal associated with the first circuit and modify the signal input into the second circuit. The feedback circuit may include a latch circuit configured to receive portions of the signal and receive a first control signal and a second control signal to tune portions of the signal.
