An autonomous compute storage device system includes an autonomous compute storage device signature/application provisioning system coupled to a storage device. The storage device retrieves an autonomous compute signature from the autonomous compute storage device signature/application provisioning system and, as part of a storage operation being performed in a storage subsystem in the storage device, stores data in a memory subsystem that is accessible to the storage device. If the storage device determines that the autonomous compute signature matches the data that was stored in the memory subsystem, it retrieves an autonomous compute application from the autonomous compute storage device signature/application provisioning system, and executes the autonomous compute application to perform compute operations that are associated with the data that was stored in the memory subsystem and generate at least one compute operation result.

An autonomous compute storage device system includes a computing device and a storage device that is coupled to the computing device.

Each at least one storage device identifies read disturb information associated with rows provided by the at least one physical block in that storage device from at least one physical block in that storage device, and maps the read disturb information associated with the rows provided by the at least one physical block in that storage device to one or more logical storage elements included in a logical-to-physical storage element mapping for that storage device to generate a local logical storage element read temperature map. Each at least one storage device may then provide its local logical storage element read temperature map to the global read temperature identification subsystem.

An autonomous compute storage device system includes a computing device and a storage device that is coupled to the computing device. The storage device receives a read instruction from a host processing system in the computing device that identifies data stored in a storage subsystem included in the storage device and, in response, performs a read operation to copy the data from the storage subsystem to a memory subsystem accessible to the storage device and provide the data to the host processing system. If the storage device determines that an autonomous compute signature matches the data that was copied to the memory subsystem during the performance of the read operation, it executes an autonomous compute application to perform compute operations that are associated with the data that was copied to the memory subsystem during the performance of the read operation and generate compute operation result(s).

The storage error identification/reduction subsystem then reads the storage error identification data from the second storage location(s) and, based on the predetermined values and predetermined locations of the storage error identification data, identifies errors resulting from the reading of the storage error identification data. Based on the errors, the storage error identification/reduction subsystem determines and performs error reduction operation(s).

A read disturb information determination system includes a storage device coupled to a global read temperature identification system. The storage device reads, from a first row in a storage subsystem in the storage device, data stored in bits that were previously identified as being susceptible to read disturb effects, and error correction information associated with the data. The storage device uses the error correction information to identify a number of the bits that store portions of the data with errors and, based on the number of bits that store portions of the data with errors, determines read disturb information for the first row in the storage subsystem in the storage device. The storage device then uses the read disturb information to generate a read temperature for a second row in the storage subsystem in the storage device, and provides the read temperature to the global read temperature identification system.
