STORAGE DEVICE WITH SELF-CONTAINED INFORMATION STORAGE SPACE

摘要

A storage device with self-contained information storage space includes at least a type-I non-volatile memory and a type-II non-volatile memory which form a data storage region and an information storage region, respectively. The type-II non-volatile memory has higher endurance than the type-I non-volatile memory. The type-I and type-II non-volatile memory are connected to a controller through a parallel interface and a series interface, respectively. The storage device uses the high-storage-density type-I non-volatile memory to meet high-capacity storage space requirement and uses the high-endurance type-II non-volatile memory to store important information and therefore ensure system stability, thereby solving problems facing existing storage devices—information stored in high-storage-density memory gets damaged easily because of an increase in programming/erase (P/E) cycles thereof.

1. A storage device with self-contained information storage space, comprising:
at least a type-I non-volatile memory having high storage density and forming a data storage region for storing data; a type-II non-volatile memory forming an information storage region to store information except data, being formed from non-volatile memory except the type-I non-volatile memory, and having higher endurance than the type-I non-volatile memory; a controller connected to the type-I non-volatile memory through a parallel interface and connected to the type-II non-volatile memory through a series interface; anda communication interface port connected to the controller.
