Systems, apparatuses, and methods related to tokens to indicate completion of data storage to memory are described. An example method may include storing a number of data values by a first page in a first row of an array of memory cells responsive to receipt of a first command from a host, where the first command is associated with an open transaction token, and receiving a second command from the host to store a number of data values by a second page in the first row. The method may further include sending a safety token to the host to indicate completion of storing the number of data values by the second page in the first row.

Tokens to indicate completion of data storage

Methods, systems, and devices for communications are described. A connection may be established between a remote device that includes an imaging device and a device. Based on establishing the connection, first visual data associated with the imaging device may be received at the device. A second connection between the device and a communication device may be established, where communications between the device and the communication device may be supported via an application running at the device. Based on establishing the second connection, the visual data may be transmitted from the mobile device to the communication device via the application.

Sharing externally captured content in communications

Methods, systems, and devices for virtualized authentication device are described. A virtual device (such as a virtual machine) may be permitted to access secured data within a memory device by an authentication process. The memory device may generate cryptographic keys in portions of the memory device and assign the cryptographic keys to the virtual machines. The virtual machine may use an authentication process using the cryptographic keys to access the secure data in the memory device. The authentication process may include authenticating the identity of the virtual machine and the code operating on the virtual machine based upon comparing cryptographic keys received from the virtual machines to the assigned cryptographic keys in the partitions of the memory device. Once both the identity of the virtual machine is authenticated, the virtual machine may be permitted to access the secure data in the memory device.

Virtualized authentication device

Various examples are directed to a host device comprising a memory system, a host device memory, and a processor. The processor is programmed to receive from the memory system a first logical-to-physical (L2P) pointer message that comprises a first L2P pointer and a first digital signature. The processor executes a cryptographic operation based at least in part on the first L2P pointer and a cryptographic key and verifies the first digital signature based at least in part on the cryptographic operation. The processor caches the first L2P pointer at the host device memory.

Secure logical-to-physical caching

A system comprising a memory component including blocks, and a processing device, operatively coupled with the memory component. The processing device determines endurance values for the memory component. For each selected block of the plurality of blocks, the processing device determines an endurance estimation of the selected block based on at least one of a time to erase the selected block or an error statistic for the selected block, and updates an endurance value associated with the selected block based on the endurance estimation for the selected block. The processing device receives a write instruction to the memory component and distributes the write instruction to one or more of the blocks based on the endurance values. Other embodiments are described.

Memory sub-system for performing wear-leveling adjustments based on memory component endurance estimations

Methods, systems, and devices for memory systems for secure sequential storage devices are described. The system may identify a request for a first portion of a memory system to operate in a first configuration and a second portion of the memory system to operate in a second configuration. The system may enter, a first power mode having a lower power consumption than a second power mode based on receiving the request and store a first address associated with a last information to be stored in the first portion of the memory system before the first portion entered the first power mode. In some cases, the memory system may enter the second power mode based on storing the first address, read the first address, and store data in a second address consecutively indexed after the first address based on reading the first address.

Memory systems for secure sequential storage devices

Methods, systems, and devices for secure storage device verification with multiple computing devices are described. A secure storage device may receive from a computing device a first command and a first public key of a first key pair associated with the computing device. The secure storage device may select a second key pair from a plurality of key pairs to associate with the computing device based on receiving the first command and the first public key. The secure storage device may also encrypt a second public key of the second key pair using the first public received from the computing device based on selecting the second key pair. The secure storage device may transmit to the computing device a message that includes the encrypted second public key.
