Abstract: A method is described for performing a wipe-out and verification of a plurality of non-volatile memory (NVM) cells. The method includes performing an operation to set all the plurality of NVM cells to a single state. The single state may be one of a conducing or non-conducting state depending on the NVM architecture. After the operation to set the cells to the single state is complete, the verification is performed. In the verification operation, all cells of the plurality of NVM cells are set to the single state by performing a single read operation on the plurality of NVM cells. Detection of one of a conducting or non-conducting path through the plurality of NVM cells is used to verify if all cells of the NVM array had their contents wiped out. A notification is provided in response to all cells not being set to the single known state.

Abstract: An ultra-wideband (UWB) system of a UWB-enabled device dynamically schedules UWB ranging sessions with multiple asynchronous access control devices. The UWB system creates one ranging session for each access control device and schedules each ranging session with equal priority. During each ranging session, the UWB system receives a ranging message from a corresponding access control device, with the ranging message including a ranging management list (RML) that includes identifiers associated with UWB systems that are within an access control range of the corresponding access control device. The UWB system updates the priority of each ranging session based on presence or absence of the corresponding identifier in the RML of the received ranging message. Further, the UWB system schedules the ranging sessions with the updated priority to dynamically prioritize one access control device, thereby enabling an operation between the UWB system and the corresponding access control device.
