示例性测试包括但不限于坏块测试。
Exemplary testing includes but is not limited to bad block testing.
如果有坏块,是否不可以继续编程?
此控制装置包括坏块映射表以及控制器。
This control device includes a bad block mapping table and a controller.
三个最重大的挑战分别是垃圾收集、管理坏块和平均读写。
The three most important are garbage collection, managing bad blocks, and wear leveling.
有一天,错误报告指出在其中一个磁盘上坏块无法重新定位。
One day, the error report started logging problems about a bad block being unable to relocate itself on one of the disks.
无法告诉服务器,“回到发生坏块重定位错误之前的状态!”
There was no way to tell the server, "Take back that bad block relocation error!"
识别出坏块后,将在flash内部将这些坏块标记到一个坏块表中。
After bad blocks have been identified, they are marked within the flash itself in a bad block table.
从分析可以看出,岩石破坏块度的对数正态分布与材料的多重破坏有关。
It is demonstrated that lognormal distribution is closely related to the multi-fold fracture of the material.
表现在破坏块体的尺寸上,最小的破坏尺寸与所能达到的强度有直接的关系。
As for the size of fractured rock, it is related with the dynamic strength which rock mass can reach.
用的时间长了,flash设备就会出现坏块,甚至在出厂时就会因出现坏块而不能使用。
Over time, flash devices can develop bad blocks through use and can even ship from the manufacturer with blocks that are bad and cannot be used.
但突然发现电脑屏幕出现了坏块,而且越来越大,一会儿时间都指甲盖那么大了。
But I abruptly see the appeared bad dot on the computer screen, see it getting larger and larger. Just for a while, it has already been the same size of fingernail.
前面提到flash设备属于耗损品:在变成坏块以前,可以执行有限次数的反复的Erase操作(因此必须由坏块管理进行标记)。
Recall that flash devices are consumable parts: You can perform a finite number of Erase cycles on each block before the block becomes bad (and must therefore be tagged by bad block management).
如果flash操作(例如Erase)失败,或者Write 操作无效(通过无效的错误校正代码发现,Error Correction Code,ECC),那么说明出现了坏块。
You can detect the presence of back blocks from a failed flash operation (such as an Erase) or an invalid Write operation (discovered through an invalid Error Correction Code, or ECC).
