Abstract: A channel width can depend on a quantity of memory units (e.g., memory dice) that forms a channel as well as a size of the memory units. A memory system can operate with memory units configured to exchange (e.g., transfer to and/or from) data at a rate of smaller granularity that can provide more various options for channel widths, which can further allow a fine-tuned optimization of the memory system in association with its bandwidth and latency in transferring data from and/or to the memory units. The channels whose channel width is fine-tuned with such memory units can be further used to provide a reliability, availability, and serviceability (RAS) protection, such as a redundant array of independent disks (RAID) protection.

Abstract: A full-text search index for a table stored in a set of partitions of a database is refreshed. At a first point in time, table row distribution information and a table partitioning list are captured. At a second point in time, it is determined that an index refresh operation is to be performed.
