    • A three-dimensional memory array and method for storing data bits and ECC bits therein is provided. A three-dimensional memory array of the type that includes multiple vertically-stacked layers of memory cells is described. The three-dimensional memory array comprises a plurality of memory cells arranged in a plurality of physically-independent sub-arrays, and data bits and error checking and correcting (ECC) bits of a word are stored in respective ones of the physically-independent sub-arrays. By spatially diffusing data bits and ECC bits from a word, the likelihood of multiple-bit errors within the word is reduced. This is advantageous since most ECC circuitry is capable of correcting only single-bit errors within a given word.
    • 提供了一种用于存储数据位和ECC位的三维存储器阵列和方法。 描述了包括多个垂直堆叠的存储单元层的类型的三维存储器阵列。 三维存储器阵列包括布置在多个物理上独立的子阵列中的多个存储器单元,并且字的数据位和错误校验和校正(ECC)位被存储在物理上独立的子 - 阵营 通过从字中空间扩散数据位和ECC位,减少字内多位错误的可能性。 这是有利的,因为大多数ECC电路仅能够校正给定字中的单位错误。
