Problems solved by technology

Although memory blocks including defective pages are managed as bad blocks, there may be no problem with two-dimensional flash memory
However, since the three-dimensional flash memory includes a small number of memory blocks and the block size of the three-dimensional flash memory is large, a problem may occur when a memory block including a defective page is managed as a bad block

Embodiment Construction

[0049] Embodiments will now be described in detail with reference to the accompanying drawings. However, the inventive concept may be embodied in many different forms and should not be construed as limited to only the illustrated embodiments. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the inventive concept to those skilled in the art. Thus, well-known procedures, elements and techniques will not be described with respect to some embodiments of the inventive concept. Unless stated otherwise, the same reference numerals are used to refer to the same elements throughout the drawings and the written description. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0050] It will be understood that although the terms "first", "second", "third" etc. may be used herein to describe various elements, components, regions, layers and / or sections, these el...

Abstract

In one embodiment, a method includes, at a memory controller, determining a condition of a selected page of memory based on a program / erase cycle count for a block of memory. A block of memory consists of selected pages. The program / erase cycle count indicates the number of times the block has been erased. A condition is selected from multiple condition states. Condition states include normal state, weak state and bad state.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority from Korean Patent Application No. 10-2013-0040221 filed on Apr. 12, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The inventive concepts described herein relate to methods of operating a storage controller and / or data storage devices including the storage controller. Background technique [0004] Semiconductor storage devices may include volatile storage devices such as DRAM, SRAM, and the like, and nonvolatile storage devices such as EEPROM, FRAM, PRAM, MRAM, flash memory, and the like. While a volatile memory device loses data stored therein when power is turned off, a nonvolatile memory device can retain data stored therein even when power is turned off. In particular, flash memory may have advantages such as fast programming speed, low power consumption, storing large amounts of data, and the like. Therefore, data storage...
