Memory card apparatus for memory capacity updating system, updates available memory capacity information according to occurrence of bad memory in memory and translates updated available memory capacity information to host device

摘要

A controller controls a non-volatile memory and communicates with a host device. The controller updates available memory capacity information that is stored in a predetermined card-specific data (CSD) register according to occurrence of bad memory in the memory and translates the updated available memory capacity information to the host device.
