Abstract: A method, an apparatus, and a computer program product for optimally tuning a memory card in a host device are provided. The apparatus determines at least one tuning parameter associated with the memory card, initiates a reading operation with the memory card, and sends a tuning command to the memory card based on the at least one tuning parameter. The at least one tuning parameter includes a temperature of the memory card, a time elapsed since a last tuning sequence was performed, a number of data blocks sent from the memory card to the host device, and/or a number of transactions between the memory card and the host device. The apparatus also reads data from the memory card, detects a cyclic redundancy check (CRC) error associated with the read data, and sends the tuning command to the memory card upon detecting the CRC error.

Abstract: Methods, apparatuses, systems, and computer-readable media for dynamically improving performance of a host memory controller and a hosted memory device are presented. According to one or more aspects, a memory controller may establish a data connection with a memory device. The memory controller may perform a first write operation of a plurality of write operations to the memory device using a first block size. Subsequently, the memory controller may perform a second write operation of the plurality of write operations to the memory device using a second block size different from the first block size. The memory controller then may determine an optimal value for a block size parameter based at least in part on the plurality of write operations. Thereafter, the memory controller may use the optimal value for the block size parameter in performing one or more regular tasks involving the memory device.
