Abstract: Methods, systems, and devices for skipping pages for weak wordlines of a memory device during pre-programming are described. A memory device may be configured to operate in a first mode involving skipping one or more pages (e.g., a lower page (LP)) associated with a set of wordlines. In some examples, a testing system may determine the set of wordlines (e.g., weak wordlines) for which to skip pages according to performance degradation for the wordlines in response to applying a threshold temperature to a test memory device. In the first mode, the memory device may store (e.g., pre-program) data in a subset of pages distinct from the skipped pages. The memory device may switch to a second mode in response to a trigger condition. In the second mode, the memory device may use each page associated with the wordlines and may refrain from skipping the one or more pages.

Abstract: An apparatus and method for authenticating a user of a vapour generating system include emitting a transmitted signal from a mouthpiece of the system into an oral cavity of the user and detecting a received signal that includes reflections of the transmitted signal from the tongue of the user. The received signal is analysed to derive characteristics of it that include Doppler shifts resulting from the tongue moving towards or away from the receiver. Operation of the system is enabled only if the user moves their tongue in a predetermined pattern, for example by inaudibly speaking a password, so that the derived characteristics match corresponding characteristics of the authorized user that have been stored in a preliminary training step. The predetermined pattern of movement of the tongue is not easy for an unauthorized person to detect or to reproduce. The transmitted signal may be a high frequency acoustic signal.
