Non-volatile memory systems and methods of managing power of the same

摘要

A non-volatile memory system and a method of managing the power of the same are provided. The non-volatile memory system includes a non-volatile memory configured to store a first mapping table comprising a list of a logical address and a physical address corresponding to the logical address with respect to a code region and a list of a logical address and a physical address corresponding to the logical address with respect to a general purpose (GP) region, and a controller configured to load the first mapping table from the non-volatile memory to a first memory and load the second mapping table from the non-volatile memory to a second memory. Power-up of the second memory is delayed with respect to power-up of the non-volatile memory system and the first or second memory is powered down if a condition is satisfied, so that power consumption of the non-volatile memory system is reduced.

1. A non-volatile memory system comprising:
a first volatile memory; a second volatile memory; a non-volatile memory configured to store a first mapping table including address information of a code region in the non-volatile memory and a second mapping table including address information of a general purpose (GP) region in the non-volatile memory, the GP region configured to store at least one of user data and an application program; and a controller configured to load the first mapping table from the non-volatile memory to the first volatile memory and load the second mapping table from the non-volatile memory to the second volatile memory, the second volatile memory being configured to receive a voltage independently of the controller, and wherein the non-volatile memory system is configured to provide a second volatile memory power supply to the second volatile memory after providing a controller power supply to the controller.
