摘要： In programming a selected word line of memory cells, a first program verify or read operation is performed, after one page of a selected word line is programmed, in order to determine a first quantity of memory cells that have been programmed to a predetermined reference point in the programmed first page distribution. Prior to programming the second page of the selected word line, a second program verify or read operation is performed to determine a second quantity of cells that are still at the reference point. The difference between the first and second quantities is an indication of the quantity of cells that experienced quick charge loss. The difference is used to determine an adjustment voltage for the second page verification operation after programming of the second page.

摘要： Methods and apparatuses for refreshing non-volatile memories due to changes in memory cell charges, such as charge loss, are disclosed. Embodiments generally comprise a voltage generator to create a sub-threshold voltage for a memory state of memory cells in a block. Once the sub-threshold voltage is applied to a word line a state reader determines states of memory cells coupled to the word line. If the state reader determines that one or more of the memory cells coupled to the word line is in the memory state, despite the sub-threshold voltage, a memory refresher may program a number of memory cells in the block. Method embodiments generally comprise applying a sub-threshold voltage to a word line for a plurality of memory cells, detecting at least one memory cell of the plurality violates a state parameter, and refreshing a block of memory cells associated with the plurality of cells.

摘要： An apparatus and technique for testing of multi-level cells (MLC) in a memory storage device using a high bandwidth data path architecture. The technique includes hardware for obtaining a first data and a second data from a multilevel cell memory. The first data is different from the second data. The first data and second data are compared and, based at least in part on this comparison, the multilevel cell memory is programmed. Programming the multilevel cell memory includes accessing memory cells in the multilevel cell memory and determining the number of bits per memory cell of the first data that need programming.
