The sensing system moves a read point two-dimensionally within a two-dimensional read space as the two-dimensional read space shrinks and shifts over the life of the chip.
Abstract: Disclosed are methods for reading a set of bits from a NVM array (such as a SPI or parallel NOR NVM or otherwise) including: retrieving each of the set of bits from the NVM array substantially in parallel, applying substantially in parallel to each of the retrieved bits a segmented search, each search indexed using an order number of the respective bit being checked, and correcting a bit whose search indicates an error.
Abstract: Embodiments include a method, apparatus, and a computer program product for combining results from multiple decoders. For example, the method can include generating a network of paths based on one or more outputs associated with each of the multiple decoders. The network of paths can be scored to find an initial path with the highest path score based on scores associated with the one or more outputs. A weighting factor can be calculated for each of the multiple decoders based on a number of outputs from each of the multiple decoders included in the initial path with the highest path score. Further, the network of paths can be re-scored to find a new path with the highest path score based on the scores associated with the one or more outputs and the weighting factor for each of the multiple decoders.

Abstract: Efficient and convenient storage systems and methods are presented. In one embodiment, a fractured erase process is performed in which a pre-program process, erase process and soft program process are initiated independently. Memory cells can be pre-programmed and conditioned independent of an erase command. The initiation of the independent pre-programming is partitioned from an erase command which is partitioned from initiation of a soft-programming command. A cell is erased wherein the erasing includes erase operations that are partitioned from the pre-preprogramming process. In one embodiment, the independent pre-program process is run in the background.
