Solid state storage system for uniformly using memory area and method controlling the same

摘要

A solid state storage system includes a memory area having a plurality of pages and is capable of storing program information about each page. The memory area stores the number of pulse counts applied to each page. A main memory controller receives the program information from the memory area and determines whether to program pages according to the program information. The main memory controller determines whether the program information for a page is at a predetermined amount and if the corresponding page should be programmed again or not.

主权项

1. A method of controlling a data storage system, comprising:
programming each of a plurality of pages of a nonvolatile memory device by repeating a program loop; providing a program loop count of each of the plurality of pages to a memory controller; comparing a critical value and the program loop count of each of the plurality of pages, respectively; and accessing the plurality of pages based upon the comparing result.
