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: In a memory device including an array of memory cells, each memory cell having more than two possible states, a method for programming a memory cell to a desired state. The method comprises a control engine programming a subset of the array of memory cells. Characterization information is determined from the step of programming the subset, wherein the characterization information indicates programming characteristics of a representative memory cell of the array of memory cells. The control engine then uses the characterization information to directly program the memory cell to approximately the desired state without performing a program verify operation.

摘要: Apparatus and methods are disclosed, such as those involving a flash memory device. One such apparatus includes a memory block including a plurality of memory cells; and a data randomizer configured to randomly or pseudo-randomly change original data to be stored in the memory block to changed data. The original data is changed such that a pattern of data as stored in the memory block is different than what it would have been if the original data had been stored in the memory block during a write operation. This configuration can reduce or eliminate data pattern-dependent errors in data digits stored in memory cells.
