Abstract: Methods, systems, and devices for temperature-based memory management are described. A system may include a memory device and a host device. The host device may identify a temperature (e.g., of the memory device). The host device may determine a value for a parameter for operating the memory device—such as a timing, voltage, or frequency parameter—based on the temperature of the memory device. The host device may transmit signaling to the memory device or another component of the system based on the value of the parameter. In some cases, the host device may determine the temperature of the memory device based on an indication (e.g., provided by the memory device). In some cases, the host device may determine the temperature of the memory device based on a temperature of the host device or a temperature of another component of the system.

Abstract: Methods, systems, and devices for controlled and mode-dependent heating of a memory device are described. In various examples, a memory device or an apparatus that includes a memory device may have circuitry configured to heat the memory device. The circuitry configured to heat the memory device may be activated, deactivated, or otherwise operated based on an indication of a temperature (e.g., of the memory device). In some examples, activating or otherwise operating the circuitry configured to heat the memory device may be based on an operating mode (e.g., of the memory device), which may be associated with certain access operations or operational states (e.g., of the memory device). Various operations or operating modes (e.g., of the memory device) may also be based on indications of a temperature (e.g., of the memory device).

Abstract: Methods, systems, and devices for drive strength calibration for multi-level signaling are described. A driver may be configured to have an initial drive strength and to drive an output pin of a transmitting device toward an intermediate voltage level of a multi-level modulation scheme, where the output pin is coupled with a receiving device via a channel. The receiving device may generate, and the transmitting device may receive, a feedback signal indicating a relationship between the resulting voltage of the channel and an value for the intermediate voltage level. The transmitting device may determine and configure the driver to use an adjusted drive strength for the intermediate voltage level based on the feedback signal. The driver may be calibrated (e.g., independently) for each intermediate voltage level of the multi-level modulation scheme. Further, the driver may be calibrated for the associated channel.

Abstract: Systems, apparatuses, and methods for training procedures on reference voltages and sampling times associated with symbols communicated with a memory device are described. The training procedures may be configured to compensate for variations that may occur in different symbols of a signal. For example, an individual training operation may be performed for each reference voltage within a first unit interval. These individual training operations may allow a reference voltage of the first unit interval to be positionable independent of other reference voltages in the same unit interval or in different unit intervals. In another example, an individual training operation may be performed for the sampling time associated with a reference voltage. These individual training operations may allow a sampling time associated with a reference voltage in the first unit interval to be positionable independent of other sampling times in the same unit interval or in different unit intervals.

Abstract: Methods, systems, and devices for reporting control information errors are described. A state of a memory array may be monitored during operation. After detecting an error (e.g., in received control information), the memory device may enter a first state (e.g., a locked state) and may indicate to a host device that an error was detected, the state of the memory array before the error was detected , and/or at least a portion of a control signal carrying the received control information. The host device may diagnose a cause of the error based on receiving the indication of the error and/or the copy of the control signal. After identifying and/or resolving the cause of the error, the host device may transmit one or more commands (e.g., unlocking the memory device and returning the memory array to the original state) based on receiving the original state from the memory device.

Abstract: Methods, systems, and devices for pre-distortion of multi-level signaling are described. A device may identify two multi-level signals that are to be transmitted over two transmission lines at the same time. The device may estimate the crosstalk expected to be caused by one of the multi-level signals on the other during propagation. Based on the expected crosstalk, the device may generate a signal that compensates for the expected crosstalk. In some examples, the signal may be a combination of the first signal and a cancelation signal. In some examples, once the compensated signal has been generated, it is transmitted over its respective transmission line at the same time that the other multi-level is transmitted over its respective transmission line.

Abstract: Methods, systems, and devices for receive-side crosstalk cancelation are described. A device that receives multiple signals over different transmission lines may include a circuit for canceling crosstalk. The circuit may include one or more capacitors or inductors that are coupled with the inputs of multiple receive circuits. The circuit may also include a set of resistors that are coupled with the receive circuits. In some cases, the device may dynamically configure the cancelation circuit to provide a particular bandwidth or strength of cancelation. In such cases, the device may configure the circuit autonomously or based on control information from another device.

Abstract: Methods, systems, and devices for indicating data corruption are described. A memory system may be configured to identify and store corrupted data received from a host system without storing metadata. As part of transmitting a bulk transmission, the host system may transmit first data to be stored at an address of the memory system, and a first indication identifying that the first data is corrupted. The memory system may generate second data with a pattern of bits indicating that data stored at the address of the memory system is corrupted. The memory system may store the second data to the address, and later retrieve the second data in response to receiving a read command from the host system. Then, the memory system may generate a second indication identifying that the second data is corrupted, and transmit the second data and the second indication to the host system.
