Patent attributes
Systems and methods are disclosed for open block refresh management. In certain embodiments, an apparatus may comprise a circuit configured to monitor an amount of time a block of a solid-state memory remains in an open state where the block has not been fully filled with data, and in response to reaching an open block time limit, compare an amount of the block already written with data against a threshold amount. When less than a threshold amount of the block has been written with data, the circuit may refresh data from a last N pages from the block by writing the data to a new location, N being a number of pages less than all pages in the block. When more than the threshold amount of the block has been written with data, the circuit may fill a remaining unwritten amount of the block with dummy data.
