Abstract: Methods, systems, and devices for setting switching for single-level cells (SLCs) are described. A memory system may receive an access command from a host. The access command may correspond to an SLC block or to a multiple-level cell block. If the access command corresponds to an SLC block, the memory system may modify the access command to include one or more bits indicating a setting to use for performing the access operation corresponding to the access command. The setting may define one or more operating parameters for performing the access operation. The memory system may use bits to indicate the setting that are used to indicate a page address for multiple-level cell blocks. The memory system may issue the access command to a memory device, which may perform the access operation using the setting indicated in the one or more bits included by the memory system.

Abstract: This invention discloses a method, device, and system for the direct electrolysis of seawater without desalination for hydrogen production. By immersing the direct electrolysis device for hydrogen production from seawater without desalination directly into seawater, driven by the pressure difference at the interface between seawater and the self-driven electrolyte, seawater continuously enters the device through the solution mass transfer layer. The self-driven electrolyte induces the water to enter the electrolyte solution, while the hydrophobic action of the solution mass transfer layer effectively blocks non-water impurities in the solution. During electrolysis, the water in the self-driven electrolyte is consumed to produce hydrogen and oxygen, inducing the regeneration of the electrolyte, maintaining the pressure difference at the interface, and achieving a self-circulating excitation drive without additional energy consumption.

Abstract: Embodiments of this application provide a communication method and apparatus. The apparatus includes a receiving module and a sending module. When the receiving module receives a user equipment UE capability query message sent by a network device, the sending module sends a first UE capability message (including a first UE capability specification) to the network device, and when determining that a network exception occurs, sends a second UE capability message (including a second UE capability specification that is lower than the first UE capability specification) to the network device. This helps implement mutual compatibility between the terminal device and the network device, thereby ensuring that a communication link can be quickly established between the terminal device and the network device. In this way, a user can normally use the terminal device, and the terminal device can keep using a high-standard network as much as possible, thereby improving user experience.
