Abstract: Methods and apparatus are provided for detection and decoding in flash memories with selective binary and non-binary decoding. Data from a flash memory device is processed by obtaining one or more read values for a plurality of bits from one or more pages of the flash memory device; converting; the one or more read values for the plurality of bits to a non-binary log likelihood ratio based on a probability that a given data pattern was written to the plurality of bits when a particular pattern was read from the plurality of bits; and jointly decoding the plurality of bits using the non-binary log likelihood ratio, wherein the pages are encoded independently.

Abstract translation: 提供了用于具有选择性二进制和非二进制解码的闪存中的检测和解码的方法和装置。 来自闪存设备的数据通过从闪存设备的一个或多个页面获得多个位的一个或多个读取值来处理; 转换 基于当从多个比特读取特定模式时将给定数据模式写入多个比特的概率，将所述多个比特的一个或多个读取值提高为非二进制对数似然比; 并使用非二进制对数似然比联合解码多个比特，其中页面被独立编码。
