Abstract: In a storage device having a storage controller and multiple memory channels, each memory channel has a memory channel controller. The storage controller, in response to a host command to perform a respective read operation at a logical address specified by the host command, identifies the memory channel based on the specified logical address, and also identifies a portion of logical to physical address mapping information corresponding to the logical address. The storage controller sends to a controller of the identified memory channel a read command that includes information identifying the portion of logical to physical address mapping information corresponding to the logical address. Using that information, the memory channel controller translates the logical address into a physical address and reads data from the physical address.

Abstract: A query may be received at a computing device through a network. One or more attribute values that are preferences for a subset of the one or more terms of the query may be identified by the computing device. One or more products or services having associated attributes that have values that match a subset of the identified attribute values may be identified by the computing device, and a subset of the identified products or services may be presented by the computing device through the network. Implementations may also identify latent preferences, that is, preferences that are found for a query even where such a preference is not explicitly part of a term or token of the query.
