ALGORITHM FOR OPTIMAL USAGE OF EXTERNAL MEMORY TUNING SEQUENCE

摘要

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.
