    摘要: The present disclosure includes methods, devices, and systems for data integrity in memory controllers. One memory controller embodiment includes a host interface and first error detection circuitry coupled to the host interface. The memory controller can include a memory interface and second error detection circuitry coupled to the memory interface. The first error detection circuitry can be configured to calculate error detection data for data received from the host interface and to check the integrity of data transmitted to the host interface. The second error detection circuitry can be configured to calculate error correction data for data and first error correction data transmitted to the memory interface and to check integrity of data and first error correction data received from the memory interface.

    摘要: The present disclosure includes methods, devices, modules, and systems for operating semiconductor memory. A number of method embodiments include reading data from memory cells corresponding to a sector of data, determining a number of the memory cells in a non-erased state, and, if the number of the memory cells in a non-erased state is less than or equal to a number of errors correctable by an ECC engine, determining the sector is erased.

    摘要: The present disclosure includes methods and devices for a memory controller. In one or more embodiments, a memory controller includes a plurality of back end channels, and a command queue communicatively coupled to the plurality of back end channels. The command queue is configured to hold host commands received from a host. Circuitry is configured to generate a number of back end commands at least in response to a number of the host commands in the command queue, and distribute the number of back end commands to a number of the plurality of back end channels.
