A memory device stores data for a host. In one approach, a trim operation is initiated for the memory device (e.g., based on a context that is determined for the memory device). During the trim operation, read and/or write tests are performed on one or more portions of a non-volatile storage media of the memory device. One or more characteristics associated with the memory device are observed during the test. Based on these observed characteristics, one or more trim settings are determined. Then, the memory device is updated to store the determined trim settings to configure subsequent read or write access to the non-volatile storage media (e.g., access performed in response to commands from a host).

Adjusting trim settings to improve memory performance or reliability

Systems, apparatuses, and methods related to transferring data to a memory device based on importance are described. A memory apparatus includes a first memory device, a second memory device having a lower write latency than the first memory device, and a controller coupled to the first memory device and second memory device via a compute express link (CXL) interface. The controller is configured to assign an importance level to a write request based on data associated with the write request, a hierarchy of importance levels for different data types, and the second memory device having a lower write latency than the first memory device. The controller is further configured to transfer the data to the first memory device in response to the assigned importance level having a first value and transfer the data to the second memory device in response to the assigned importance level having a second value.

Transferring data to a memory device based on importance

A memory device includes a memory cell array, a voltage generation circuit generating one or more voltages supplied to the memory cell array, an input/output circuit receiving an address indicating a region in the memory cell array, and a control circuit controlling operations of the memory cell array. The control circuit supplies a non-selection voltage of the voltages before a ready/busy signal changes from a ready state to a busy state.

An apparatus configured to allow data values to be written into the plurality of memory cells of the memory device at a first speed upon connecting to a first host via a first configuration of the plurality of connectors; and allow data values to be written into the plurality of memory cells at a second speed faster than the first speed, upon connecting to a second host via a second configuration of the plurality of connectors.

Multiple pin configurations of memory devices

A system for crowdsourcing reporting of road conditions from abnormal vehicle events. Abnormal vehicle events (such as sudden braking, sharp turns, evasive actions, pothole impact, etc.) can be detected and reported to a road condition monitoring system (RCMS). The RCMS can identify patterns in reported road conditions to generate advisory information or instructions for vehicles and users of vehicles. For example, suspected obstacles can be identified and used to instruct a driver or a vehicle to slow down gradually to avoid sudden braking and sharp turns. In some examples, a vehicle can have a camera that can upload an image of a suspected obstacle (e.g., a pothole) to allow the positive identification of a road problem. This provides the RCMS with more confidence to take a corrective action, such as an automated call to a road repair service.

Crowdsourcing road conditions from abnormal vehicle events

A semiconductor storage device in an embodiment includes a plurality of planes each including a memory cell array, a voltage generation circuit configured to apply a first intermediate voltage to an adjacent word line adjacent to a selected word line in a former half of a program period and apply a second intermediate voltage higher than the first intermediate voltage to the adjacent word line in a latter half of the program period, a discharge circuit configured to feed a discharge current from the selected word line in a period corresponding to a period in which the second intermediate voltage is applied to the adjacent word line, and a control circuit configured to set a discharge characteristic of the discharge circuit according to a number of the planes.

A data storage device stores data in non-volatile memory. In one approach, a method includes: storing software in a compressed format in a first mode (e.g., an SLC mode) in a non-volatile memory; exposing, while the software is stored in the first mode, the non-volatile memory to a temperature greater than a predetermined threshold; determining that the temperature of the non-volatile memory has fallen below the predetermined threshold; and in response to determining that the temperature of the non-volatile memory has fallen below the predetermined threshold: decompressing the stored software, and storing the decompressed software in a second mode (e.g., TLC mode) in the non-volatile memory. The second mode has a storage density higher than the first mode.

Controlling firmware storage density based on temperature detection

A method includes detecting an event occurring on a vehicle. The vehicle includes at least one computing device that controls at least one operation of the vehicle. The at least one computing device includes a first computing device comprising system memory. In response to detecting the event, data is downloaded from the system memory to a non-volatile memory device of the vehicle. In some cases, a control action for the vehicle is implemented based on analysis of the downloaded data.

Downloading system memory data in response to event detection

A system can train a vehicle electronically to accommodate a driver. The system can train the vehicle to accommodate the ability, condition, and/or personality of the driver. The system can change the controls of the vehicle, responsive to the inputs from the driver, to match with the patterns of controls resulting from a predetermined model (such as a safe-driver model). Accordingly, the vehicle can appear as it is being driven by a safe driver when it may not be the case. A driver with a lower driving competence may apply physical controls in a pattern that may be slow, unstable, or insufficient. However, the vehicle can be trained to adjust the transformation from the UI signals to the drive-by-wire signals such that the transformed signals appear to be applied by a more competent driver on the road. And, the transformation can improve over time with training via machine learning.

Training a vehicle to accommodate a driver

A memory device includes a memory cell array, a voltage generation circuit generating one or more voltages supplied to the memory cell array, an input/output circuit receiving an address indicating a region in the memory cell array and a control circuit controlling operations of the memory cell array. The voltage generation circuit generates the voltages before a ready/busy signal changing from a ready state to a busy state.

A method for an autonomous vehicle includes: controlling at least one system of the vehicle by a host system; automatically collecting, by a memory device, data generated by the at least one system, where the data is collected by the memory device independently of control by the host system; and storing the data in the memory device.

Automatic collection of autonomous vehicle logging data

A data storage device monitors a storage media temperature and adjusts data storage operations of the storage device based on the monitored and/or a predicted future temperature of the storage media. In one approach, data is stored in a first mode (e.g., a TLC mode) in a non-volatile storage media. One or more temperatures associated with the non-volatile storage media are monitored using at least one sensor to collect sensor data. The manner of storage of the data in the storage device is adjusted based on the collected sensor data. The adjusting comprises compressing the data to provide compressed data, and storing the compressed data in a second mode (e.g., an SLC mode) in the non-volatile storage media.

Temperature-based data storage processing

A display device of an autonomous vehicle is controlled based on data collected from sensors located in or on the vehicle. The display device is used to present one or more images to a driver and/or passengers of the autonomous vehicle. The display device can be, for example, a windshield and/or other window of the vehicle. Image data can be, for example, transformed to improve visual perception by passengers in the vehicle when the images are displayed on a curved shape of the windshield.

Control of display device for autonomous vehicle

A semiconductor memory device includes: a memory cell array; a peripheral circuit connected to this memory cell array, the peripheral circuit outputting data in the memory cell array as a read data in response to input of a command set, the command set including a first command, address data, and a second command; a first electrode capable of being used in input of the command set and output of the read data; and a second electrode capable of supplying electric power to the peripheral circuit. A current flowing in the second electrode at a second timing is larger than a current flowing in the second electrode at a first timing, the first timing being a timing at which the first command is inputted, the second timing being a timing before which the input of the address data is started and after which an input of the second command is finished.
