  • Publication number: 20260037053
    Abstract: A memory device can operate in multiple powerdown modes. A first powerdown mode powers down a memory rank by powering down one or more command address (CA) input buffers completely (e.g., turn off). A second powerdown mode powers down a memory rank by powering down one or more command address (CA) input buffers incompletely (e.g., a reduced operational state). In a non-limiting nonexclusive embodiment, the second powerdown mode powers down the one or more CA input buffers by placing the one or more CA input buffers in a low bias current state.

  • Publication number: 20260037133
    Abstract: Apparatuses, systems, and methods for setting termination impedance based on encoding bits are disclosed. A memory receives an access command including one or more encoding bits, which may be received via one or more CA pins. Based on the one or more encoding bits and a setting in a mode register, the memory determines whether it is a target of the access command, and the memory applies a termination impedance based at least in part on the determination of whether it is the target of the access command. In various embodiments, the determination of whether the memory is the target can be performed in a single cycle.

  • Publication number: 20250389572
    Abstract: Disclosed herein are devices, systems, and methods for accurately determining fluid level using Ultra Wideband (UWB) positioning or localization. UWB utilizes a radio-frequency (RF) technology to enable the accurate measurement of the time-of-flight of a radio signal and UWB positioning can operate in Time-Difference-of-Arrival (TDoA) mode, Two-Way-Ranging (TWR) mode, and Phase-Difference-of-Arrival (PDoA) mode. The systems disclosed herein include multiple anchor devices having a UWB antenna(s) and positioned in fixed location(s) over the fluid to be measured. The anchor devices serve as reference points for UWB communication with a remote float device, which emits RF signals and floats on the surface of the fluid to be measured.
