    • A method for data storage includes storing data in a memory including multiple analog memory cells arranged in blocks. A first subset of the blocks is defined for storing first data with a first storage density, and a second subset of the blocks is defined for storing second data with a second storage density, larger than the first storage density. In each of the first and second subsets, one or more blocks are allocated to serve as spare blocks and blocks that become faulty are replaced with the spare blocks. Upon detecting that a number of the spare blocks in the second subset has decreased below a predefined threshold, the data is copied from at least one block in the second subset to the first subset, and the at least one block is added to the spare blocks of the second subset.
    • 用于数据存储的方法包括将数据存储在包括以块为单位的多个模拟存储单元的存储器中。 定义块的第一子集用于存储具有第一存储密度的第一数据,并且限定块的第二子集用于存储具有大于第一存储密度的第二存储密度的第二数据。 在第一和第二子集中的每一个中,一个或多个块被分配用作备用块,并且变得有故障的块被替换为备用块。 在检测到第二子集中的多个备用块已经降低到低于预定义阈值时,将数据从第二子集中的至少一个块复制到第一子集,并且至少一个块被添加到备用块 的第二个子集。

    • Methods, apparatus and computer readable medium for handling error correction in a memory are disclosed. In some embodiments, after an attempt is made to write original data to a 'target' memory, data is read back from the target memory in a 'first read operation', thereby generating first read data. After the first read operation, the first read data is compared to the original data and/or an indication of a difference between the original data and the first data is determined. The information obtained by effecting the data-comparison and/or information related to the difference indication is used when correcting errors in data read back from the target memory in a 'second read operation.'. The presently-disclosed teachings are applicable to any kind of memory including (i) non-volatile memories such as flash memory, magnetic memory and optical storage and (ii) volatile memory such as SRAM or DRAM.
    • 公开了一种用于处理存储器中的纠错的方法,装置和计算机可读介质。 在一些实施例中,在尝试将原始数据写入“目标”存储器之后,以“第一读取操作”从目标存储器读回数据,从而生成第一读取数据。 在第一读取操作之后,将第一读取数据与原始数据进行比较和/或确定原始数据与第一数据之间的差异的指示。 当在“第二读取操作”中校正从目标存储器读回的数据中的错误时,使用通过进行与差异指示相关的数据比较和/或信息而获得的信息。 目前公开的教导可应用于包括(i)诸如闪存,磁存储器和光存储器的非易失性存储器和(ii)诸如SRAM或DRAM之类的易失性存储器的任何种类的存储器。
