Abstract
Aspects of a storage device including a memory and a controller are provided. In certain aspects, the controller may determine that data stored on a first block satisfies a threshold data-error condition, the data comprising invalid data and valid data. For example, the first block may have a high ratio of valid data to invalid data that satisfies or exceeds a threshold value. In certain aspects, the controller may determine a close block boundary associated with the first block, wherein the close block boundary is configured to bifurcate the first block into a first portion and a second portion, wherein the first portion comprises the data. For example, the controller may determine a boundary defined by a data length, an indirection mapping unit, a physical program boundary, etc.
