Abstract: A magnetic tracking device includes a sensor configured to generate a sensor electromotive force (EMF). The device includes a mechanism configured to select between a first operating mode in which the sensor generates the sensor EMF when receiving the magnetic field and a second operating mode in which the sensor generates a reduced amount of the sensor EMF when receiving the magnetic field.

Abstract: Instead of using trees to group key values (KV) based on KV information, use host provided information for grouping KVs. In the cases where the host provides KV information, the host determines how to group the information. The controller will then use the KV information to store the KV information in a group. The KVs can be sorted in the group by either size, length, type, etc. of the KV received from the host. Independent backend logic, such as data routing management, parity management, block management, and proactive data retrieval, is used to group KV information. Grouping the KV information using the independent backend logic will make garbage collection (GC) less difficult and increase retrieval performance due to the grouping of the KVs.

Abstract: Technology for reading memory cells in three-dimensional memory having multiple tiers. The memory system erases the tiers within each block independently. Then, memory cells in the tiers are programmed by units such as word lines. The memory system determines one or more read parameters for the selected tier based on the programmed/erased states of the other tiers in the block. For example, the memory system may select read reference levels for the selected tier based on the programmed/erased states of the other tiers. In an aspect, the one or more read parameters are used to determine the set of reference voltages for a bit error rate estimation scan (BES).
