Abstract: A method for estimating the pressure measurement bias of a barometric sensor in a wireless terminal. A location engine using the method generates an enhanced estimate of the measurement bias. The location engine generates the enhanced estimate based in part on Global Navigation Satellite System (GNSS)-based estimates of the elevation of the wireless terminal, which the terminal generates as it concurrently makes barometric pressure measurements. Each GNSS-based estimate of elevation is often generated from noisy measurements and has an associated uncertainty. The location engine accounts for the uncertainty in the GNSS estimates of elevation by applying an optimal estimation technique, such as Kalman filtering, on the biased pressure measurements and the GNSS-based estimates.

Abstract: A programming operation is performed on a first set of memory cells addressable by a first wordline (WL), wherein the first set of memory cells are comprised by an open translation unit (TU) of memory cells. It is determined that a second set of memory cells comprised by the open TU are in a coarse programming state, wherein the second set of memory cells is addressable by a second WL. In response to determining that the second set of memory cells satisfies a threshold criterion, a programming state verify level associated with the second WL is reduced by a verify level offset. A programming state gate step size associated with each WL of the open TU is reduced by a predefined value. A programming operation is performed on the second set of memory cells using the reduced programming state verify level and the reduced programming state gate step size.

Abstract: A magnetic tunnel junction (MTJ) is disclosed wherein first and second interfaces of a free layer (FL) with a first metal oxide (Hk enhancing layer) and second metal oxide (tunnel barrier), respectively, produce perpendicular magnetic anisotropy (PMA) to increase thermal stability. In some embodiments, a capping layer that is a conductive metal nitride such as MoN contacts an opposite surface of the Hk enhancing layer with respect to the first interface to reduce interdiffusion of oxygen and nitrogen compared with a TiN capping layer and maintain an acceptable resistance×area (RA) product.
