Abstract: Aspects of a storage device including a memory and a controller are provided, which allow for error detection or data integrity checking during data transfer of write operations and read operations. The controller may be configured to generate data integrity information based on at least one data byte to be written to the memory, and to transfer the at least one data byte contemporaneously with the data integrity information on separate data paths to the memory. The controller may be configured to select between transferring data bus inversion information or the data integrity information based on whether a data integrity protection mode is active between the memory and the controller. The memory may be configured to receive the at least one data byte and the data integrity information from the controller, and detect whether an error exists in the at least one data byte based on the data integrity information.

Abstract: A computing storage architecture is disclosed. Memory devices may incorporate distributed processors and memory. The devices can be arranged using multiple packages, each package including one, or multiple, dies. In one aspect of the disclosure, any of the processors on a first die may transfer data to and from any processor on a second die internally within the device without having to pass through an external storage controller. In another aspect of the disclosure, a multi-package processing architecture allows for both in-package and inter-channel data transfers between processors within the same device. In still another aspect of the disclosure, one or more processors may include a preemptive scheduler circuit, which enables a processor to interrupt an ongoing lower priority transmission and to immediately transfer data.
