Abstract: System and methods for enhanced data processing and analysis in a storage device, such as a solid state drive (SSD) include an SSD having a data storage and a controller. The data storage stores a plurality of data sets. The controller has a pattern buffer and a data engine. The controller receives a query, processes the query to extract a pattern, loads the pattern into the pattern buffer, and accesses the data storage. The data engine searches a data subset from the data storage for instances of the pattern using a rolling window method. The controller generates a result from the search.

Abstract: A system and method of providing enhanced data processing and analysis in a storage device, such as a solid state drive (SSD). The SSD includes flash memory and an SSD controller capable of executing searches on the data in the flash memory without returning all of the data to be searched to a host CPU outside of the SSD. Other processing capabilities incorporated into the SSD may include encryption and decryption, compression and decompression, and in-line indexing of data. The SSD efficiently processes queries through the use of an internal data buffer and a data engine configured to search partial data.

Abstract: A system and method for operating a solid state drive (SSD) within power limitations while maintaining SSD performance. In one embodiment a power management integrated circuit (PMIC) is used to measure power consumption, and a built-in self-test (BIST) procedure is used to exercise the storage device, and to calibrate the power consumed by various SSD operations. The results are stored in a power consumption cost table. In one embodiment, a procedure to dynamically adjust the power consumption cost table is employed. A power credit allocation scheme is used, along with the power consumption cost table, to track and limit the power consumed by the SSD in operation.

Abstract: A system and method for storing infrequently accessed data with reduced power consumption. In one embodiment, a solid state drive (SSD) includes flash memory and environmental data logging circuitry. The SSD is shut off or operated in a sleep mode to reduce power consumption, and turned on or transitioned to an active mode as needed when data on the SSD is to be accessed, or when a calculation, based on a number of erase cycles previously performed in the flash memory and on a temperature history of the SSD indicates that a data refresh may be needed to prevent data corruption in the SSD, due to data retention limitation of the nonvolatile memory in the SSD.
